>if Churchill and the British had their way, D-Day might not have happened. They did everything they could to head off the American plan to attack across the English Channel. They pressed instead for a strategy focused on the Mediterranean, pushing through the “soft underbelly” of southern Europe, over the Alps and through the Balkans. The Americans prevailed because they provided an increasingly larger share of the forces and funding. The British opposition to Overlord has dimmed in memory and today is largely forgotten. Churchill played it down as best he could in his memoirs, but there was already too much on record to leave any doubt about the effort to delay, divert, or avoid the D-Day invasion.

Here's my question, if Churchill and Roosevelt had been on the same page about the need to contain the Soviet Union in addition to stopping Nazi Germany and agreed on an invasion of Yugoslavia in 1943/44 in lieu of Italy or Normandy, would it have been feasible? What challenges and opportunities did it present that invading through France didn't? How differently would WWII have played out had it been done?
