Why Hitler Kept so Many Troops in Norway in WWII?

Nazi Germany maintained 300,000 to 400,000 soldiers in Norway during World War II for strategic and economic reasons. Controlling Norway provided Germany with access to vital resources, particularly iron ore from Sweden, which was transported through Norwegian ports. Additionally, Norway's geographical location allowed Germany to dominate the sea routes of the North Atlantic, preventing the Allies from establishing naval blockades and threatening German supply lines. The rugged terrain and harsh weather conditions in Norway made it a challenging theater of operations, and the Germans wanted to secure this region against potential Allied attempts to cut off their access to crucial resources. Furthermore, Norway served as a base for German U-boats, enabling them to launch submarine operations against Allied convoys in the Atlantic. The occupation of Norway was, therefore, a multifaceted strategy that encompassed economic interests, strategic positioning, and naval warfare considerations.
