Swedish neutrality and nonalignment policy in peacetime may partly explain how the country could stay out of wars since 1814. Swedish governments have not defined nonalignment as precluding outspoken positions in international affairs. Government leaders have favored national liberation movements that enjoy broad support among developing world countries, with notable attention to Africa. During the Cold War, Sweden was suspicious of the superpowers, which it saw as making decisions affecting small countries without always consulting those countries. With the end of the Cold War, that suspicion has lessened somewhat, although Sweden still chooses to remain nonaligned. Sweden has devoted particular attention to issues of disarmament, arms control, and nuclear nonproliferation and has contributed importantly to UN and other international peacekeeping efforts, including the NATO-led peacekeeping forces in the Balkans. It sat as an observer in the Western European Union from 1995 to 2011, but it is not an active member of NATO's Partnership for Peace and the Euro-Atlantic Partnership Council.
