If we are discussing D-Day in 1943 it is probably worth linking these earlier, often spirited discussions:
Among the extreme detail arguments presented in these threads there are a couple of general facts that can be assumed. Bear in mind these threads assume OTL until at least early 1942.
1. Any invasion of France in 1943 would be majority Commonwealth. The US could not bring enough formations up to strength and get them to Britain in 1943 to be the majority partner. At most they may achieve parity.
2. In spite of this an American Supreme Commander is still likely. Marshal is suggested as Eisenhower probably doesn’t yet have the prestige to be appointed when the bulk of the forces under him are not American and won’t be for some time.
3. For the invasion to go ahead the decision must be made in mid to late 1942. Otherwise the necessary material is not available.
4. This will cause a reduction of effort in the Pacific to a degree. Though @Eric C Johnson who was heavily involved in the first thread and mostly wrote the next two as OP, beleivws that this would lead to a much larger effort in 1944-45 as larger forces are moved from Europe to the Pacific in light of German defeat in 1944.
Certainly not everyone is convinced it was possible. Personally I was, but others had their own, valid, reasons for being sceptical.
