Switzerland: Switzerland maintained its traditional policy of neutrality throughout the war. The country's neutrality was respected by both the Allies and the Axis, allowing it to serve as a refuge for displaced people and as a meeting place for diplomatic negotiations.
Sweden: Sweden also remained neutral during the war. While the country had strong economic and cultural ties to Germany, it stayed out of the conflict to maintain its sovereignty and independence.
Ireland: Ireland chose to remain neutral during the war due to its complex political and historical situation. The country had recently gained independence from the United Kingdom and sought to avoid involvement in international conflicts.
Portugal: Portugal remained neutral throughout the war, despite pressure from both the Allies and the Axis. The country's strategic location on the Iberian Peninsula allowed it to maintain a delicate balance between the warring parties.
Turkey: Turkey declared neutrality at the outbreak of the war but maintained close relations with both the Allies and the Axis. It eventually joined the Allied powers in February 1945, shortly before the end of the war.
Afghanistan: Afghanistan remained neutral during the war, pursuing a policy of non-interference in global affairs.
It's worth noting that the concept of neutrality can be complex and nuanced. Some countries may have maintained a formal policy of neutrality while still providing economic or political support to one side of the conflict. Additionally, some countries that initially declared neutrality eventually joined one of the belligerent parties as the war progressed.
