First term foreign policy

Four basic principles undergirded Roosevelt's foreign policy approach when he took office. As Arthur M. Schlesinger Jr. explains: :One was TR's nowiki/> nowiki/>Theodore_Roosevelt's">Theodore_Roosevelt.html"_;"title="nowiki/>Theodore_Roosevelt">nowiki/>Theodore_Roosevelt'sbelief_in_the_preservation_of_the_balance_of_world_power._A_second_was_Wilson's_dream_of_concerted_international_action_to_keep_the_peace._The_third_was_the_conviction_that_peace_and_political_collaboration_rested_on_commercial_harmony_among_nations_and_therefore_required_a_freely_trading_world._The_fourth_principle_was_the_imperative_necessary_in_a_democracy_of_basing_foreign-policy_on_domestic_consent._The_first_three_principles_were_inevitably_qualified_and_compromised_by_the_fourth.

A second was Wilson's dream of concerted international action to keep the peace. The third was the conviction that peace and political collaboration rested on commercial harmony among nations and therefore required a freely trading world. The fourth principle was the imperative necessary in a democracy of basing foreign-policy on domestic consent. The first three principles were inevitably qualified and compromised by the fourth. Having served as the Assistant Secretary of the Navy in World War I, Roosevelt had a deep understanding of United States Navy">naval affairs and knew many of the senior officers. He kept abreast of naval issues and appreciated the doctrines of Alfred Thayer Mahan on the need for naval superiority.

Recognition of the Soviet Union

By the late 1920s, the Soviet Union was no longer a pariah in European affairs, and had normal diplomatic and trade relations with most countries. By 1933, old American fears of Communist threats had faded, and the business community, as well as newspaper editors, were calling for diplomatic recognition. Roosevelt was eager for large-scale trade with Russia, and hoped for some repayment on the old tsarist debts. After the Soviets promised they would not engage in espionage, Roosevelt used presidential authority to normalize relations in November 1933. There were few complaints about the move. There was no progress on the debt issue, however, and the Kremlin set up an active espionage program. Many American businesses had expected a bonus in terms of large-scale trade, but it never materialized. Historians Justus D. Doenecke and Mark A. Stoler note that, "Both nations were soon disillusioned by the accord."

Rague, argues this reduced the strength of the Court, discredited America's image as a proponent of international law, and exemplified the problems created by vesting a reservation power in the Senate.


Neutrality laws block response to aggression

Roosevelt took office a few weeks after Hitler did in Germany and quickly spotted the aggressive nature of the new Nazi regime. He instructed the American representative to Geneva to say that if there was a threat to peace the United States was willing to cooperate with collective efforts made by other states to restore peace. Congress however immediately rejected this initiative by requiring that any embargo on arms shipments to aggressor nations, had to apply equally to victims of aggression. The neutrality laws of the mid-1930s forbade the president to discriminate between aggressor and victim, which effectively prevented Roosevelt from acting against aggression. When Congress rejected his proposal to join the world World Court, FDR commented, "Today, quite frankly, the wind everywhere blows against us." The 1930s marked the high point of American

. The country had a long tradition of non-interventionism, but isolationists in the 1930s sought to keep the U.S. out of world affairs to an unprecedented degree. Isolationist sentiment stemmed from a desire to focus on domestic issues, bitterness over World War I and unpaid war debts, and fears that bankers (many of them Jewish like the Rothschilds) and munitions makers intrigued to involve the United States and European wars in order to make profits. public opinion showed a strong detachment from, and reluctance to become involved in, the growing crises in Europe. Responding to the country's isolationist mood, Roosevelt in the 1930s never mentioned his previous support for joining the

. Britain and France remained neutral and worked to get the major powers to agree to an arms embargo on both sides. In solidarity with them, Roosevelt recommended to Congress a nondiscriminatory arms embargo in January 1937, and won near-unanimous approval. Though privately supportive of the Republicans, Roosevelt feared the Spanish crisis might escalate to a full-scale European war and cooperated with the other democracies to contain the conflict. He also did not want to alienate American Catholics, a key element of his coalition; Catholic leaders were mostly pro-Franco. By spring 1938, as it was clear that Hitler and Mussolini were aiding Franco, Roosevelt was considering a plan to secretly sell American warplanes to the Spanish government, but nothing came of it. As the Nationalists were on the road to victory in early 1939, Roosevelt would refer to the embargo as a mistake. Britain and France recognized Franco's regime on February 27, 1939 and Roosevelt followed on April 1, days after Franco achieved full victory with the capture of Madrid.

Relations with France

In the 1930s the diplomatic relations between the United States and France were minimal. The United States did not figure in French plans until 1938. The embassies had little business beyond assisting tourists and businessmen, but there was practically no high-level activity. French foreign-policy was very busy indeed with the growth of Nazi Germany after 1933, putting to a severe test the French policy of forming military alliances with Germany's smaller neighbors, such as Czechoslovakia and Poland. In dramatic contrast the United States basked in complete security. President Hoover did set up a world economic conference in spring 1933 to come up with international solutions to the depression, but Roosevelt torpedoed it by rejecting any possible recommendations. And the United States moved into an almost complete isolation from European affairs.

France suddenly became aware of its drastic inferiority in airpower—Germany had better warplanes, more of them, pilots with combat experience, and much bigger and more efficient factories. Paris made an enormous effort to catch up by expanding its military budget, giving priority to aviation, standardizing its models, building new factories, and making overseas purchases. France expected to be powerful in the air by 1941, and in combination with Britain, to have more airpower than Germany by then. In late 1937 Paris sent to Washington a personal friend of Roosevelt, Senator Baron Amaury de La Grange. He told Roosevelt about the French weaknesses, and urgently asked for help. Roosevelt was never an isolationist, strongly opposed Nazi Germany, and was eager to help France. He also realized that a large French order would greatly speed up the expansion of the American aircraft industry. Roosevelt forced the War Department to secretly sell the most modern American airplanes to France. Paris frantically expanded its own aircraft production, but it was too little and too late.

During the so-called " Phony War," a period of inactivity in Western Europe following the conclusion of the invasion of Poland, Roosevelt tried to negotiate a peace, but Hitler was uninterested in such a possibility. Japan, meanwhile, grew increasingly assertive in the Pacific, demanding that the French and British colonies close their borders with China.

and bombed British targets, further galvanized American public opinion behind Britain but definitely short of war. Overcoming the opposition of much of the military establishment, who doubted Britain's ability to remain in the war against Germany, Roosevelt pursued policies designed to maximize arms transfers to Britain and overcoming the opposition of much of the government, Roosevelt rejected the convoy escort across the Atlantic for one more year. In July 1940, Roosevelt appointed two interventionist Republican leaders, Henry L. Stimson and Frank Knox, as Secretaries of War and the Navy, respectively. Both parties gave support to his plans for a rapid build-up the American military, but Roosevelt himself sided with the isolationists in not getting the nation into a war with Germany. Consequently, both Stimson and Knox the following year were disappointed, puzzled, and "shocked" by FDR’s isolationist line, or “failure of leadership,” as they called it. The military build-up and the British purchase of armaments had a beneficial effect on the economy, and the unemployment rate fell to 14.6 percent in late 1940. On September 2, 1940, Roosevelt defied the spirit of the Neutrality Acts in reaching the

. The Tripartite Act was specifically designed to intimidate the United States into remaining neutral in the Sino-Japanese War and the war in Europe. As Roosevelt took a firmer stance against the Axis Powers, American isolationists like Lindbergh and America First vehemently attacked the president as an irresponsible warmonger. In turn they were denounced as anti-Semitic dupes of the Nazis. Reviewer Richard S. Faulkner paraphrases Lynne Olson in arguing that, "Lindbergh was far from the simple anti-Semite and pro-Nazi dupe that the Roosevelt administration and pro-intervention press often portrayed him to be, but was rather a man whose technical and clinical mind had him convinced that Britain could not win the war and America’s lack of military preparedness meant that intervention was immoral, illogical, and suicidal."


Prelude to war: 1941

After his reelection in 1940 the world war dominated FDR's attention, with far more time devoted to world affairs than ever before. Domestic politics and relations with Congress were largely shaped by his efforts to achieve total mobilization of the nation's economic, financial, and institutional resources for the war effort. Even relationships with Latin America and Canada were structured by wartime demands. Roosevelt maintained tight personal control of all major diplomatic and military decisions, working closely with his generals and admirals, the war and Navy departments, Churchill and the British, and even with the Soviet Union.

in the 1940 presidential election, Roosevelt embarked on a public campaign to win congressional support for aid to the British. In December 1940, Roosevelt received a letter from Churchill asking the U.S. to repeal the cash and carry provision of the Neutrality Act. With British forces committed to defending against Germany, Churchill asked for the United States to provide loans and shipping for American goods. In response, Roosevelt delivered a speech in which he called for the United States to serve as the " Arsenal of Democracy," supplying aid to those resisting Germany and other aggressors. He stated, "if Great Britain goes down, the Axis Powers will control the continents of

With the backing of Willkie, the Lend-Lease bill passed by large majorities in both houses of Congress, with most of the opposition coming from Midwestern Republicans.

Roosevelt also requested, and Congress, granted, a major boost in military expenditures. With this boost in spending, the

strategy and the avoidance of conflict with Japan for as long as possible. A key part of this strategy was to ensure that Britain remained in the fight against Germany until the United States, potentially with the aid of other countries, could launch a land offensive into Europe. Roosevelt did not publicly commit to Plan Dog, but it motivated him to launch talks between American and British military staff, codenamed " ABC–1." In early 1941, American and British military planners jointly agreed to pursue a Europe first strategy. In July 1941, Roosevelt ordered Secretary of War Stimson to begin planning for total American military involvement. The resulting "Victory Program" provided the army's estimates of the mobilization of manpower, industry, and logistics necessary to defeat Germany and Japan. The program planned to dramatically increase aid to the Allied nations and to prepare a force of ten million men in arms, half of whom would be ready for deployment abroad in 1943. When Germany

Execution of the aid fell victim to foot dragging in the administration, so FDR appointed a special assistant,

On 4 September 1941 an American destroyer the USS ''Greer'' (DD-145), which was carrying mail and passengers to Allied-occupied Iceland, tracked a German submarine but did not fire on it. The German U-boat U-652 fired two torpedoes at the Greer, which evaded them. Neither warship was damaged. In response, Roosevelt announced a new policy in which the U.S. would attack German or Italian ships that entered U.S. naval zones. This "shoot on sight" policy effectively declared naval war on Germany and was favored by Americans by a margin of 2-to-1. However, this episode did not escalate into all-out war, because both Hitler and Roosevelt were very cautious. Hitler needed to devote all his military resources to his invasion of the Soviet Union, and Roosevelt wanted to build up public support for an aggressive policy to control the North Atlantic. Roosevelt Sent the military to establish American bases in

Following the attack, Congress amended the Neutrality Act to allow American merchant ships to transport war supplies to Britain, effectively repealing the last provision of the cash and carry policy. However, neither the ''Kearny'' incident nor an attack on the '' USS ''Reuben James'''' changed public opinion as much as Roosevelt hoped they might.

Tojo succeeded Konoye as prime minister in October, and the Japanese began preparations for an attack on the United States. In November, Nomura made a final offer, asking for reopened trade and acceptance of the Japanese campaign in China in return for Japan's pledge not to attack Southeast Asia. In large part because the U.S. feared that Japan would attack the Soviet Union after conquering China, Roosevelt declined the offer, and negotiations collapsed on November 26.

that Washington knew in advance. The Japanese had kept their secrets closely guarded, and while senior American officials were aware that war was imminent, they did not expect an attack on Pearl Harbor. Roosevelt had anticipated that the first attack would take place in the Dutch East Indies, Thailand, or the Philippines.


World War II 1941–1945

After Pearl Harbor, antiwar sentiment in the United States evaporated overnight. For the first time since the early 19th century, foreign policy became the top priority for the American public. Roosevelt called for war in his famous " Infamy Speech" to Congress, in which he said: "Yesterday, December 7, 1941 — a date which will live in infamy — the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan." On December 8, Congress voted almost unanimously to declare war against Japan. On December 11, 1941, Germany and Italy

on the United States, which responded in kind. Roosevelt portrayed the war as a crusade against the aggressive dictatorships that threatened peace and democracy throughout the world. He and his military advisers implemented a war strategy with the objectives of halting the German advances in the Soviet Union and in North Africa; launching an invasion of western Europe with the aim of crushing Nazi Germany between two fronts; and saving China and defeating Japan. Public opinion, however, gave priority to the destruction of Japan, so American forces were sent chiefly to the Pacific in 1942. Japan launched an aerial attack on American forces in the Philippines just hours after the attack on Pearl Harbor. By the end of the month, the Japanese had launched an invasion of the Philippines.

the ruler of China. Chiang's regime virtually collapsed under Japanese pressures in 1944, and Japan overran the American airbases that were built to attack Japan. The Pentagon's plans to use China as a base to destroy Japan collapsed, so the U.S. Air Force turned its attention to attacking Japan with very long-range B-29 bombers based in the Pacific. The American military no longer needed China or Southeast Asia. China clearly was too weak to be a policeman. With the defeat of Japan, Britain took over Southeast Asia and returned Indochina to France. Roosevelt realized his trusteeship plan was dead, and accepted the British-French actions as necessary to stabilize Southeast Asia.

provided energetic leadership. Under Rockefeller's leadership, the U.S. spent millions on radio broadcasts, motion pictures, and other anti-fascist propaganda. American advertising techniques generated a push back in Mexico, especially, where well-informed locals resisted heavy-handed American influence. Nevertheless, Mexico was a valuable ally in the war. A deal was reached whereby 250,000 Mexican citizens living in the United States served in the American forces; over 1000 were killed in combat. In addition to propaganda, large sums were allocated for economic support and development. On the whole the Roosevelt policy in Latin America was a political success, except in Argentina, which tolerated German influence, and refused to follow Washington's lead until the war was practically over. Outside of Latin America, the U.S. paid particularly close attention to its oil-rich allies in the Middle East, marking the start of sustained American engagement in the region.


Lend-Lease and economic warfare

The main American role in the war, beyond the military mission itself, was financing the war and providing large quantities of munitions and civilian goods. Lend lease, as passed by Congress in 1941, was a declaration of economic warfare, and that economic warfare continued after the attack on Pearl Harbor. Roosevelt believed that the financing of World War I through loans to the Allies, with the demand for repayment after the war, had been a mistake. He set up the Lend Lease system as a war program, financed through the military budget. As soon as the war with Japan ended it was terminated. The president chose the leadership—

played major roles—and exercised close oversight and control. One problem that bedeviled the program in 1942 was the strictly limited supply of munitions that had to be divided between Lend Lease and American forces. Roosevelt insisted to the military that the Soviet Union was to get all the supplies he had promised it. Lend-lease aid to the Soviet Union declined somewhat in mid-1942 after the United States began to prepare for military operations in North Africa. The U.S. spent about $40 billion on Lend Lease aid to the British Empire, the Soviet Union, France, China, and some smaller countries. That amounted to about 11% of the cost of the war to the U.S. It received back about $7.8 billion in goods and services provided by the recipients to the United States, especially the cost of food and rent for American installations abroad. Britain received $30 billion, Russia received $10.7 billion, and all other countries $2.9 billion. When the question of repayment arose, Roosevelt insisted the United States did not want a postwar debt problem of the sort that had troubled relations after the first world war. The recipients provided bases and supplies to American forces on their own soil; this was referred informally as "Reverse Lend Lease," and the combined total of this aid came to approximately $7.8 billion overall. In the end, none of the Allied Powers paid for the goods received during the war, although they did pay for goods in transit that were received after the program ended. Roosevelt told Congress in June 1942: : The real costs of the war cannot be measured, nor compared, nor paid for in money. They must and are being met in blood and toil... If each country devotes roughly the same fraction of its national production to the war, then the financial burden of war is distributed equally among the United Nations in accordance with their ability to pay. A major issue in the economic war was the transportation of supplies. After Germany declared war on the United States, Hitler removed all restrictions on the German submarine fleet. German submarines ravaged Allied shipping in the Atlantic, with many of the attacks taking place within ten miles of the

s or the rail lines leading to the camps, fearing it would be a diversion from the war effort. According to biographer Jean Edward Smith, there is no evidence that anyone ever proposed such a campaign to Roosevelt himself. In sum, Roosevelt took significant but limited action regarding the persecution in Germany, the refugee crisis in the 1930s, and the systematic killing of six million Jews in gas chambers after 1941. Public and elite opinion, including the Jewish-American leadership, generated little pressure to take action. Roosevelt's legacy remains highly controversial among historians and the general public. Richard Breitman and Allan J. Lichtman state:, "This ongoing quarrel is unforgiving, passionate, and politically charged." They conclude that Roosevelt: :did more for the Jews than any other world figure, even if his efforts seem deficient in retrospect. He was a far better president for Jews than any of his political adversaries would have been. Roosevelt defied most Republican opponents and some isolationist Democrats to lead political and military opposition to Nazi Germany's plan for expansion and world domination.

Post-war planning

In late 1943, Roosevelt, Churchill, and Stalin agreed to meet to discuss strategy and post-war plans at the
Tehran Conference The Tehran Conference ( codenamed Eureka) was a strategy meeting of Joseph Stalin, Franklin Roosevelt, and Winston Churchill from 28 November to 1 December 1943, after the Anglo-Soviet invasion of Iran. It was held in the Soviet Union's embass ...
, which marked Roosevelt's first face-to-face meeting with Stalin. At the conference, Britain and the United States committed to opening a second front against Germany in 1944, while Stalin committed to entering the war against Japan at an unspecified date. Roosevelt also privately indicated acceptance of Soviet control of the
Baltic states The Baltic states, et, Balti riigid or the Baltic countries is a geopolitical term, which currently is used to group three countries: Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone ...
and Soviet plans to shift Poland's borders to the west. Stalin, meanwhile, committed to joining the war against Japan after the defeat of Germany. Post-war plans increasingly came to the fore as the Allies scored major victories in 1944. Taking up the Wilsonian mantle, Roosevelt made his highest priority the establishment of the
United Nations The United Nations (UN) is an intergovernmental organization whose stated purposes are to maintain international peace and security, develop friendly relations among nations, achieve international cooperation, and be a centre for harmoni ...
. It would be a permanent intergovernmental organization that would succeed the League of Nations. Roosevelt expected it would be controlled by Washington, Moscow, London and Beijing, and would resolve all major world problems. The wartime economic boom and the experience of the Great Depression convinced many Americans of the need to lower trade barriers. Lend-Lease agreements included provisions for eliminating tariffs, and the U.S. especially desired the dismantlement of the British

. With the end of the war in Europe approaching, Roosevelt's primary focus was on convincing Stalin to enter the war against Japan, because casualty estimates, depending on their assumptions, ranged from hundreds of thousands to millions for an Allied invasion of Japan. In return for its entrance into the war against Japan, the Soviet Union was promised control of Asian territories such as
Sakhalin Island Sakhalin ( rus, Сахали́н, r=Sakhalín, p=səxɐˈlʲin; ja, 樺太 ''Karafuto''; zh, c=, p=Kùyèdǎo, s=库页岛, t=庫頁島; Manchu: ᠰᠠᡥᠠᠯᡳᠶᠠᠨ, ''Sahaliyan''; Orok: Бугата на̄, ''Bugata nā''; Nivkh ...

and deindustrialization on Germany after the war. Roosevelt's role in the Yalta Conference has been controversial; critics charge that he naively trusted the Soviet Union to allow free elections in Eastern Europe, while supporters argue that there was little more that Roosevelt could have done for the Eastern European countries given the Soviet occupation and the need for cooperation with the Soviet Union during and after the war.


Founding the United Nations

Roosevelt had been a strong supporter of the
League of Nations The League of Nations (french: link=no, Société des Nations ) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference th ...

was FDR's highest postwar priority. He insisted on full coordination with the Republican leadership. He made sure that leading Republicans were on board, especially Senators
Arthur Vandenberg Arthur Hendrick Vandenberg Sr. (March 22, 1884April 18, 1951) was an American politician who served as a United States senator from Michigan from 1928 to 1951. A member of the Republican Party, he participated in the creation of the United Natio ...
of Michigan, and Warren Austin of Vermont. In a broad sense, Roosevelt believed that the UN could solve the minor problems and provide the chief mechanism to resolve any major Issues that arose among the great powers, all of whom had a veto. For FDR creating the UN was the most important goal for the entire war effort. Roosevelt was especially interested in international protection of human right, and in this area his wife played a major role as well. The Allies had agreed to the basic structure of the new body at the
Dumbarton Oaks Conference The Dumbarton Oaks Conference, or, more formally, the Washington Conversations on International Peace and Security Organization, was an international conference at which proposals for the establishment of a "general international organization", w ...

. Roosevelt considered the United Nations to be his most important legacy. He provided continuous backstage political support at home and with Churchill and Stalin abroad. The Big Four of the United States, Britain, Soviet Union and China would make the major decisions, with France added later to provide permanent members of the all-powerful Security Council. Each had a veto power, thus avoiding the fatal weakness of the League of Nations, which had theoretically been able to order its members to act in defiance of their own parliaments.


Anti-imperialism

British, French, and Dutch leaders all hoped to retain or reclaim their colonial possessions after the war. The U.S. was committed to granting independence to the
Commonwealth of the Philippines The Commonwealth of the Philippines ( es, Commonwealth de Filipinas or ; tl, Komonwelt ng Pilipinas) was the administrative body that governed the Philippines from 1935 to 1946, aside from a period of exile in the Second World War from 1942 ...

and pushed back hard. Because the U.S. needed British cooperation in India to support China, Roosevelt had to draw back on his anti-colonialism. That annoyed Indian nationalist leaders, though most of those leaders were in British prisons for the duration because they would not support the war against Japan. Roosevelt also believed that France had performed the poorest in governing its colonies and resisting the Axis. He advocated for the placement of French Indochina under an international trusteeship once the war ended. This was opposed by the British, who was afraid of losing its own colonies if the idea of trusteeship gathered further momentum. Roosevelt also promised to return Chinese territories seized by Japan since 1895, and ended the practice of American special rights in China.
