The Bomb and the Balkans - A connection?

As you know, I at times divert from the arts when I ponder other aspects of man's history - having taught certain phases of history; chiefly, arts history, I had dug deeply enough into various facets of the subject, resulting in such actions as having exchanged letters with the great historian, the late Stephen Ambrose.
What floated across my translucent blackboard were two incidents in the second world war, each quite a distance apart from the other, both in time and geography; however, both came under the same hypothetical question about what the world would be like today.
The first incident was Operation Dragoon, which was the Allied invasion of Southern France to enact a giant pincers formation following Operation Overlord in Northern France - D-Day.
Churchill was violently against Dragoon, and wanted instead an Allied incursion into the Balkans.
Obviously, Churchill was overruled .
The following year, the Bomb was dropped twice on Japan.
Which forged these questions upon my furrowed brow:
If Churchill had gotten his way, and the Balkans had been invaded instead of Southern France, AND was successful, what would Europe have looked like after the war? COULD there have been a Stalinist Eastern Europe? Or, a democratically designed quilt of nations east of Germany? Or, something in between? Or, war with Soviet Russia?
If the Bomb had not been dropped, and the Allies were forced to invade Japan, would the Soviet military giant have occupied Northern Japan? One has to remember that the Bomb was dropped not only for the obvious reason; specifically, the defeat of Japan, but also because of the fear of Russian troops entering Japan. Would MacArthur's epic reconstruction of Japan been possible?
What would the Far East look like today, let alone Eastern Europe?
Questions never to be answered, but I find myself in collision with this kind of question more often than not.
And I thought music was a mystery.
