Which of these countries remained neutral during World War II?

The story behind the answer

Switzerland is correct because it maintained a long-standing policy of armed neutrality throughout World War II. Surrounded by Axis powers, it mobilized its military, fortified the Alps (the National Redoubt), and used diplomacy and tightly controlled borders to deter invasion while trading cautiously with both sides.

By contrast, the United Kingdom and France declared war on Germany in 1939, and Italy joined the Axis in 1940 before switching sides in 1943. A helpful memory tip: think “Swiss Army Knife”—useful for defense, not aggression—and the Red Cross founded in Geneva, both tied to Switzerland’s neutral image. Switzerland’s neutrality had been internationally recognized since
