and some conservatives were strong advocates for entrance in the war on the German side, and the government's policy had a clear pro-German bias. In 1916, the pro-German policy was abandoned, having resulted in famine, rebellious opinions, and no tangible advantages. Once again, the conviction that strict neutrality was most suitable for Sweden dominated Swedish society. A new, less German-minded Conservative cabinet was appointed, and to calm the social unrest, democratic reforms were promptly initiated that cemented Sweden's neutralist policy and would soon lead to the political hegemony of Social Democrats lasting up to the 21st century.

Despite Sweden's grievances over failing to gain control of the islands in 1921, all difficulties between Sweden and Finland were resolved by the mid-1930s. The fear of the Ã…land islands falling under German or Soviet influence was very real, and that is why Sandler proposed defending the status of the islands.

It was initially believed that the Swedish government had dropped Sandler due to his outspoken comments on the government's policies, and the German press' allegations that Sandler was pro-British; however, in reality it was Sandler who requested permission to retire from the Swedish cabinet, because the government did not represent Sandler's anti-neutral views.


Armed neutrality

The 1930s marked a new period when Sweden's long-standing policy of neutrality was severely tested on numerous occasions, most of which came from a strongly rejuvenated nationalistic Germany. Since the founding of the
League of Nations The League of Nations (LN or LoN; , SdN) 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 (1919–1920), Paris Peace ...

Significance of the neutrality policy

The fate of the Swedish nation largely rested upon the outcomes of distant battles and the policies of distant governments—events outside the control of Swedish politicians and diplomats. Had certain battles or policies during the war been different, Sweden's ability to attain a successful policy of neutrality might very well not have succeeded. Finland was invaded by the Soviet Union in the

against the USSR. Sweden was now entirely surrounded by Nazi allies, but the German war machine would also be distracted for the remainder of the war with their struggle with the Red Army. If there were ever serious plans for a Nazi invasion of Sweden, they were put indefinitely on hold due to the more pressing struggle with the Soviets. Sweden would avoid the devastating losses and destruction that so much of Europe suffered during World War II, although how much was due to luck and how much was due to their diplomatic stance may never be clear. One beneficial consequence of Sweden's neutrality was that Sweden was able to act as a refuge to people from occupied lands. Approximately 70,000 Finnish children were evacuated and placed with families in Sweden. There were also refugees from the Baltic nations and the other Scandinavian countries. Nearly all of Denmark's Jewish population was able to escape to Sweden on fishing boats in a coordinated effort by the Danish people and the Swedes who gave them shelter on the other side. Sweden's neutral stance allowed Swedish diplomats access to Germany, allowing for espionage which benefited the Swedish intelligence as well as the Allies. The Swedish diplomats

The aim of the policy was to avoid the violent initial nuclear exchange between the superpowers. This was the rationale behind Sweden's policy of neutrality until the late 1960s with the advent of second strike capability and nuclear parity. Initially after the end of World War II, Sweden quietly pursued an aggressive independent nuclear weapons program involving plutonium production and nuclear secrets acquisition from all nuclear powers, until the 1960s, when it was abandoned as cost-prohibitive.

Sweden appeared to maintain a dual approach to thermonuclear weapons. Publicly, the strict neutrality policy was forcefully maintained, but unofficially strong ties were purportedly kept with the U.S. Sweden, for instance, cooperated extensively with U.S. intelligence: "Though officially neutral, Sweden in fact built very close ties to both NATO and the US security establishment in the late 1940s and early 1950s and was deeply involved in cold war spying operations." It was hoped that the U.S. would use conventional and nuclear weapons to strike at

in case of a Soviet attack on Sweden. Over time and due to the official neutrality policy, fewer and fewer Swedish military officials were aware of the military cooperation with the west, making such cooperation in the event of war increasingly difficult. At the same time Swedish defensive planning was completely based on help from abroad in the event of war. Later research has shown that every publicly available war-game training included the scenario that if Sweden was under attack from the Soviets, it would rely on NATO forces for defence. The fact that it was not permissible to mention this aloud eventually led to the Swedish armed forces becoming highly misbalanced. For example, a strong ability to defend against an amphibious invasion was maintained, while an ability to strike at inland staging areas was almost completely absent. In the early 1960s U.S. nuclear submarines armed with mid-range nuclear missiles of type

. The submarines had to be very close to the Swedish coast to hit their intended targets though. As a consequence of this, in 1960, the same year that the submarines were first deployed, the U.S. provided Sweden with a military security guarantee. The U.S. promised to provide military force in aid of Sweden in case of Soviet aggression. This guarantee was kept from the Swedish public until 1994, when a Swedish research commission found evidence for it. As part of the military cooperation the U.S. provided much help in the development of the

. The continued reduction of its own national defence and the question of whether the country really could defend itself against an aggressor has led to some criticism. In 2009 Sweden agreed to enter into mutual self-defence treaties with the EU, and with other Nordic countries, thus ending a nearly 200 year long period of official military neutrality. As a result of a 2010 U.S. diplomatic cables leak, it was learned that the
