Interesting comment.
Russia began ww2 allied with nazi germany and invaded Poland with Germany. Even held victory parade with Germany
Then invaded Finland, Lithuania, Latvia and Estonia.
Curious why Briton and France declared war on Germany after polish invasion but not Soviets
You might note that the “great patriotic war” didn’t begin in sept 39, but when Germany invaded Soviet Union.
As to China, the Chinese had a little thing called a communist revolution after ww2 and the Chinese govt that we were allied with fled to Taiwan, and we are more or less still allied with them
Worth remembering that the overwhelming majority of German casualties in WWII were inflicted by the Soviets. Google the battle of Kursk.
Our alliance with Stalin saved millions of Allied lives. The enemy of my enemy is my friend.
