Switzerland's extensive network of bunkers can be traced back to its historical context, particularly the threat during World War II. The country built these bunkers as a deterrent against invasion, establishing a robust defense architecture aimed at making it economically unfeasible for Nazi Germany to attack. The historical backdrop of trade collaborations with the Nazis and ambiguous neutrality raises complex discussions around Switzerland's wartime strategies. Current discussions revolve around the implications of these strategies and the legacy they leave, especially in the context of Swiss banking practices during the war.
