On This Date -A Momentous Decision For Us All

I will digress from the arts once again to remind the reader about a fateful decision made on this date - a decision that places us all where we are at this point in time.
On June 22, 1941, the greatest land war in history began when Hitler's Germany invaded Mother Russia, better known then as Soviet Russia.
Around dawn of this fateful day, some three million German troops, on a line of some two thousand miles, running north to south, stormed into Russia in order to create the lebensraum Hitler had written about in his Mein Kampf a generation before.
We give thanks, of course, for the massive blunder Hitler perpetrated upon himself by not having learned from Napoleon's experience in Russia, not to mention his turning upon his own words; that is, never to fight a war on two fronts.
After the carnage emanating from the next four years, two nations emerged as eventual Super Powers; namely, the U.S.A. and Russia, with the ensuing Cold War resulting in what we now are experiencing in a dangerous and fluidic world that has shrunk to the size of a pea.
I sometimes wonder what the world would be like today, had Hitler conquered a nation occupying approximately one sixth of the world's land mass?
Or, as the great historian Stephen Ambrose once speculated; namely, on the possibility of an alliance between Hitler and Stalin?
