Public opinion

American public opinion was divided, with most Americans until early 1917 largely of the opinion that the United States should stay out of the war. Opinion changed gradually, partly in response to German actions in Belgium and the ''Lusitania'', partly as German Americans lost influence, and partly in response to Wilson's position that America had to play a role to make the world safe for democracy. In the general public, there was little if any support for entering the war on the side of the German Empire. The great majority of German Americans, as well as

, wanted the United States to remain neutral; however, at the outbreak of war, thousands of U.S. citizens had tried to enlist in the German army. The Irish Catholic community, based in the large cities and often in control of the Democratic Party apparatus, was strongly hostile to helping Britain in any way, especially after the Easter uprising of 1916 in Ireland.

Preparedness movement

By 1915 Americans were paying much more attention to the war. The sinking of the ''Lusitania'' aroused furious denunciations of German brutality. In Eastern cities a new "Preparedness" movement emerged. It argued that the United States needed to build up immediately strong naval and land forces for defensive purposes; an unspoken assumption was that America would fight sooner or later. The driving forces behind Preparedness were all Republicans, notably General Leonard Wood, ex-president

, and former secretaries of war

The Preparedness movement had what political scientists call a "realism" philosophy of world affairs—they believed that economic strength and military muscle were more decisive than idealistic crusades focused on causes like democracy and national self-determination.

were all larger and more experienced than the United States military. They called for UMT or "universal military service" under which the 600,000 men who turned 18 every year would be required to spend six months in military training, and then be assigned to reserve units. The small regular army would primarily be a training agency. Public opinion, however, was not willing to go that far. Both the regular army and the Preparedness leaders had a low opinion of the National Guard, which they saw as politicized, provincial, poorly armed, ill trained, too inclined to idealistic crusading (as against Spain in 1898), and too lacking in understanding of world affairs. The National Guard on the other hand was securely rooted in state and local politics, with representation from a very broad cross section of the U.S. political economy. The Guard was one of the nation's few institutions that (in some northern states) accepted black men on an equal footing with white men.

Democrats respond

The Democratic party saw the Preparedness movement as a threat. Roosevelt, Root and Wood were prospective Republican presidential candidates. More subtly, the Democrats were rooted in localism that appreciated the National Guard, and the voters were hostile to the rich and powerful in the first place. Working with the Democrats who controlled Congress, Wilson was able to sidetrack the Preparedness forces. Army and Navy leaders were forced to testify before Congress to the effect that the nation's military was in excellent shape. In reality, neither the U.S. Army nor U.S. Navy was in shape for war in terms of manpower, size, military hardware or experience. The Navy had fine ships but Wilson had been using them to threaten Mexico, and the fleet's readiness had suffered. The crews of the ''

. The facts of submarine warfare (which necessitated destroyers, not battleships) and the possibilities of imminent war with the German Empire (or with Britain, for that matter), were simply ignored. Wilson's decision touched off a firestorm. Secretary of War Lindley Garrison adopted many of the proposals of the Preparedness leaders, especially their emphasis on a large federal reserves and abandonment of the National Guard. Garrison's proposals not only outraged the provincial politicians of both parties, they also offended a strongly held belief shared by the liberal wing of the Progressive movement, that was, that warfare always had a hidden economic motivation. Specifically, they warned the chief warmongers were New York bankers (such as J. P. Morgan) with millions at risk, profiteering munition makers (such as

Garrison's plan unleashed the fiercest battle in peacetime history over the relationship of military planning to national goals. In peacetime, War Department arsenals and Navy yards manufactured nearly all munitions that lacked civilian uses, including warships, artillery, naval guns, and shells. Items available on the civilian market, such as food, horses, saddles, wagons, and uniforms were always purchased from civilian contractors. Peace leaders like

of Stanford University redoubled their efforts, and now turned their voices against the President because he was "sowing the seeds of militarism, raising up a military and naval caste." Many ministers, professors, farm spokesmen and labor union leaders joined in, with powerful support from a band of four dozen southern Democrats in Congress who took control of the House Military Affairs Committee. Wilson, in deep trouble, took his cause to the people in a major speaking tour in early 1916, a warm-up for his reelection campaign that fall. Wilson seemed to have won over the middle classes, but had little impact on the largely ethnic working classes and the deeply isolationist farmers. Congress still refused to budge, so Wilson replaced Garrison as Secretary of War with Newton Baker, the Democratic mayor of Cleveland and an outspoken ''opponent'' of preparedness. The upshot was a compromise passed in May 1916, as the war raged on and Berlin was debating whether America was so weak it could be ignored. The Army was to double in size to 11,300 officers and 208,000 men, with no reserves, and a National Guard that would be enlarged in five years to 440,000 men. Summer camps on the Plattsburg model were authorized for new officers, and the government was given $20 million to build a nitrate plant of its own. Preparedness supporters were downcast, the antiwar people were jubilant. The United States would now be too weak to go to war. Colonel

battle of Jutland The Battle of Jutland (german: Skagerrakschlacht, the Battle of the Skagerrak) was a naval battle fought between Britain's Royal Navy Grand Fleet, under Admiral John Jellicoe, 1st Earl Jellicoe, Sir John Jellicoe, and the Imperial German Navy ...

(May 31/June 1, 1916) saw the main German High Seas Fleet engage in a monumental yet inconclusive clash with the far stronger Grand Fleet of the Royal Navy. Arguing this battle proved the validity of Mahanian doctrine, the navalists took control in the Senate, broke the House coalition, and authorized a rapid three-year buildup of all classes of warships. A new weapons system, naval aviation, received $3.5 million, and the government was authorized to build its own armor-plate factory. The very weakness of American military power encouraged the German Empire to start its unrestricted submarine attacks in 1917. It knew this meant war with America, but it could discount the immediate risk because the U.S. Army was negligible and the new warships would not be at sea until 1919 by which time the war would be over, Berlin thought, with the German Empire victorious. The notion that armaments led to war was turned on its head: refusal to arm in 1916 led to war in 1917.

Home front

The home front required a systematic mobilization of the entire population and the entire economy to produce the soldiers, food supplies, munitions, and money needed to win the war. It took a year to reach a satisfactory state. Although the war had already raged for two years, Washington had avoided planning, or even recognition of the problems that the British and other Allies had to solve on their home fronts. As a result, the level of confusion was high at first. Finally efficiency was achieved in 1918. 'Destroy this mad brute' WWI propaganda poster (US version)

The war came in the midst of the Progressive Era, when efficiency and expertise were highly valued. Therefore, the federal government set up a multitude of temporary agencies with 50,000 to 1,000,000 new employees to bring together the expertise necessary to redirect the economy into the production of munitions and food necessary for the war, as well as for propaganda purposes.

Finance

Clear-the-way!! Buy bonds-Fourth liberty loan - Howard Chandler Christy

In 1917 the government was unprepared for the enormous economic and financial strains of the war. Washington hurriedly took direct control of the economy. The total cost of the war came to $33 billion, which was 42 times as large as all Treasury receipts in 1916. A constitutional amendment legitimized income tax in 1913; its original very low levels were dramatically increased, especially at the demand of the Southern progressive elements.

Claude Kitchin Claude Kitchin (March 24, 1869 – May 31, 1923) was an American politician who served as a member of the United States House of Representatives from the state of North Carolina from 1901 until his death in 1923. A lifelong member of the Democra ...

, chairman of the tax-writing Ways and Means Committee argued that since Eastern businessman had been leaders in calling for war, they should pay for it. In an era when most workers earned under $1000 a year, the basic exemption was $2,000 for a family. Above that level taxes began at the 2 percent rate in 1917, jumping to 12 percent in 1918. On top of that there were surcharges of one percent for incomes above $5,000 to 65 percent for incomes above $1,000,000. As a result, the richest 22 percent of American taxpayers paid 96 percent of individual income taxes. Businesses faced a series of new taxes, especially on "excess profits" ranging from 20 percent to 80 percent on profits above pre-war levels. There were also excise taxes that everyone paid who purchased an automobile, jewelry, camera, or a motorboat. The greatest source of revenue came from war bonds, which were effectively merchandised to the masses through an elaborate innovative campaign to reach average Americans. Movie stars and other celebrities, supported by millions of posters, and an army of Four-Minute Men speakers explained the importance of buying bonds. In the third Liberty Loan campaign of 1918, more than half of all families subscribed. In total, $21 billion in bonds were sold with interest from 3.5 to 4.7 percent. The new Federal Reserve system encouraged banks to loan families money to buy bonds. All the bonds were redeemed, with interest, after the war. Before the United States entered the war, New York banks had loaned heavily to the British. After the U.S. entered in April 1917, the Treasury made $10 billion in long-term loans to Britain, France and the other allies, with the expectation the loans would be repaid after the war. Indeed, the United States insisted on repayment, which by the 1950s eventually was achieved by every country except Russia.

Labor

(AFL) and affiliated trade unions were strong supporters of the war effort. Fear of disruptions to war production by labor radicals provided the AFL political leverage to gain recognition and mediation of labor disputes, often in favor of improvements for workers. They resisted strikes in favor of arbitration and wartime policy, and wages soared as near-full employment was reached at the height of the war. The AFL unions strongly encouraged young men to enlist in the military, and fiercely opposed efforts to reduce recruiting and slow war production by pacifists, the anti-war

After initially resisting taking a stance, the IWW became actively anti-war, engaging in strikes and speeches and suffering both legal and illegal suppression by federal and local governments as well as pro-war vigilantes. The IWW was branded as anarchic, socialist, unpatriotic, alien and funded by German gold, and violent attacks on members and offices would continue into the 1920s.

Propaganda

Crucial to U.S. participation was the sweeping domestic propaganda campaign. In order to achieve this, President Wilson created the

Committee on Public Information The Committee on Public Information (1917–1919), also known as the CPI or the Creel Committee, was an independent agency of the government of the United States under the Wilson administration created to influence public opinion to support the ...

through Executive Order 2594 on April 13, 1917, which was the first state bureau in the United States that's main focus was on propaganda. The man charged by President Wilson with organizing and leading the CPI was George Creel, a once relentless journalist and political campaign organizer who would search without mercy for any bit of information that would paint a bad picture on his opponents. Creel went about his task with boundless energy. He was able to create an intricate, unprecedented propaganda system that plucked and instilled an influence on almost all phases of normal American life. In the press—as well as through photographs, movies, public meetings, and rallies—the CPI was able to douse the public with Propaganda that brought on American patriotism whilst creating an anti-German image into the young populace, further quieting the voice of the neutrality supporters. It also took control of market regarding the dissemination of war-related information on the American home front, which in turn promoted a system of voluntary censorship in the country's newspapers and magazines while simultaneously policing these same media outlets for seditious content or anti-American support. The campaign consisted of tens of thousands of government-selected community leaders giving brief carefully scripted pro-war speeches at thousands of public gatherings. Alongside government agencies were officially approved private vigilante groups like the American Protective League. They closely monitored (and sometimes harassed) people opposed to American entry into the war or displaying too much German heritage. Other forms of propaganda included newsreels, large-print posters (designed by several well-known illustrators of the day, including

American military

American women never served in combat roles (as did some Russians), but many were eager to serve as nurses and support personnel in uniform. During the course of the war, 21,498 U.S. Army nurses (American military nurses were all women then) served in military hospitals in the United States and overseas. Many of these women were positioned near to battlefields, and they tended to over a million soldiers who had been wounded or were unwell. 272 U.S. Army nurses died of disease (mainly tuberculosis, influenza, and pneumonia).

The first American women enlisted into the regular armed forces were 13,000 women admitted into active duty in the U.S. Navy during the war. They served stateside in jobs and received the same benefits and responsibilities as men, including identical pay (US$28.75 per month), and were treated as veterans after the war. The U.S. Marine Corps enlisted 305 female Marine Reservists (F) to "free men to fight" by filling positions such as clerks and telephone operators on the home front.

However, many American commanders used the same flawed tactics which the British, French, Germans and others had abandoned early in the war, and so many American offensives were not particularly effective. Pershing continued to commit troops to these full-frontal attacks, resulting in high casualties without noticeable military success against experienced veteran German and Austrian-Hungarian units. Nevertheless, the infusion of new and fresh U.S. troops greatly strengthened the Allies' ''strategic position'' and boosted morale.
