In hindsight, historical and strategic considerations seem to fully justify postponing the Normandy invasion from 1943 to 1944. Only in 1944 had three fundamental objectives for a cross-Channel invasion been achieved. The Allies had agreed on a coherent, viable strategy. They had achieved peak strength in terms of combat experience, naval and air supremacy, military intelligence, and logistical readiness. It had also been decided that the German war machine had been sufficiently weakened.
