I know this is a well known question but I wonder if an Allied invasion of Normandy in 1943 could have succeeded. The Allies put 150,000 men ashore on Sicily in July 1943 with massive air support. If the same forces had assaulted France instead more German divisions would have fought than were on Sicily but the Allies would still have been hard to stop. Anyone have an opinion on the chances of Allied success and the strength of German forces in France in May or June 1943? I expect an Allied build up in southern England would have been detected by the Germans and maybe they would have never attacked at Kursk in order to have more divisions in France.
