Arguments against invading France before 1944:
- Germany's military strength was still formidable, making an invasion risky and potentially costly.
- The Allies did not have the necessary resources and logistical capabilities for a large-scale amphibious operation across the English Channel.
- The Allies were concerned that the French population might be hostile towards the invasion and engage in resistance activities.
- The Allies were already heavily engaged in other campaigns, such as the Mediterranean campaign and the bombing campaign against Germany.
