It is ungrateful not to mention the losses that Russia suffered in WWII. Granted they were fighting for their own rear ends, but their sacrifices did buy us time, because they bought England time.
It was dicey enough landing in Normandy, France, with England as the staging area. Without England, I can't imagine what we would have done. Where would we have flown bombing missions from if we didn't have England?
And buying time for us, the Russians gave us time to build The Bomb. It was originally intended for Hilter, but became very useful in ending WWII in the Pacific Theatre and probably saved hundreds of thousands of U.S. lives and probably over a million Japanese lives.
Yes, we all know about Russia declaring war on Japan after The Bomb was dropped. And about a lot else, which is why we fought a "cold" war with for half a century after WWII.
And now we face a kind of return of Napoleon from Elba in Putin's hand in glove alliances with all our enemies in the Middle East and Asia.
So, I have no blinkers on about Russia. But they did buy England and thus the U.S. time.
It is ungrateful to bash the US for taking two years fighting in the Pacific before we could start another front. If it was so easy why didn't Russia fight on two fronts?
