Question

Why were the early months of World War 2 referred to as the Phony War?

Neither side really believed the other would fight
France and Germany waited for the other to attack and nothing happened.
France and Great Britain refused to fight in the war
France was tricked into believing that Germany did not want to attack
What was Hitler’s strategy for attacking France first?

Answer 1

Hitler's strategy for attacking France first was to bypass the heavily fortified Maginot Line and launch a surprise invasion through the Ardennes Forest, which was considered to be impassable for tank divisions. This strategy proved successful as German forces quickly advanced through the Ardennes and outflanked French defenses, ultimately leading to the fall of France in just six weeks.
