Gerhard Weinberg and Jay Williams discuss Hitler's defining decision to launch a major offensive against the Americans and British in the west instead of focusing on the Soviet Union in the east. Hitler, the Chief of State, acting as Commander in Chief of the Wehrmacht, overrode the judgement of his military advisers, going against military logic and previously strategic decisions. He sent some of his best troops, the men who stood between the Red Army and their march to Berlin, to fight the Americans and British in Belgium. The reasons behind this decision - whether psychological as Hitler tied the fate of the Third Reich to that of victory, strategic as he believed a surprise offense had worked before and could work again, or something else entirely, was a crucial error.
