Final answer:
Switzerland, Sweden, Spain, and Portugal remained neutral during WWII, as did Ireland and Turkey, although Turkey joined the Allies in February 1945. These countries managed to maintain a policy of neutrality while the war raged across Europe.
Step-by-step explanation:
The countries that remained neutral during World War II (WWII) can be identified from historical records and maps of the period. Considering the information provided including the Cold War alliance map and historical context, countries such as Switzerland, Sweden, Spain, and Portugal maintained a policy of neutrality throughout the conflict. The map you referred to might depict these nations, and potentially others such as Ireland and Turkey, which also adopted a neutral stance, although Turkey later joined the Allies in February 1945.
Switzerland and Sweden are particularly noted for their policies of armed neutrality, where they maintained a strong military force to deter aggression while not taking part in the fighting. Spain, under Francisco Franco, and Portugal, led by António de Oliveira Salazar, remained officially neutral but had varying degrees of informal cooperation with the Axis and the Allies. Ireland maintained its neutrality throughout the war despite pressure and geographical proximity to the United Kingdom.
