Your greatest generation must also include Russia and England's generations then right since we didn't really enter the war until 1942 while Russia lost over 24 million soldiers and civilians to our 418,000. Germany doesn't lose WW2 if Hitler didn't go full retard and attack Russia or stop from invading England or spread his army ridiculously thin over an area with a square footage the size of all of Africa or doesn't freeze all his troops to death in wintery cold as 17 Russia. USA doesn't really get to take credit for saving all of Europe, North Africa and half of Asia when the ultimate reason was a psychotic moron going full retard on his army and we didn't enter the fight till 3 years into it.
I get so tired of these myths that the Red Army fought defeated the Nazis in the East alone. It's complete revisionist history. Also, comparing number of deaths doesn't linearly measure the sacrifice of a nation. The Russians were shooting their own soldiers in the back for cowardice. Just because one country has more deaths during a war doesn't mean they should be more highly commended - maybe they just aren't very good at it. The truth is without the industrious might of the United States (Capitalism) that supplied and fed Russia through the early days of the war in the East, Moscow, Stalingrad, and Leningrad fall along with the entirety of Russia. Hell, Stalin signed a truce with Hitler, and they were deciding how to divide up Poland among Germany and Russia before Hitler broke that truce. Very noble.
US Eagle squadrons were fighting in the air over the English Channel pre official US involvement in the war, and the only reason we weren't on the western side of the continent until 1944 was because it was completely occupied by the Nazis. US and British fought their way onto the continent through North Africa, and were in Italy by 1943. Not to mention we were fighting another war on the other side of the world completely alone in the pacific. Yes- other countries played a role in the war, but the fact is that the war could not have been won without the United States. The same can't be said for Canada, Belgium or whomever else. Period. I'll end this with Churchill's quote upon hearing the news of Pearl Harbor. He knew what US involvement ultimately meant for the world.
"So, we had won after all! …We had won the war. England would live; Britain would live; the Commonwealth of Nations and the Empire would live. How long the war would last or in what fashion it would end no man could tell, nor did I at this moment care. . . . We should not be wiped out. Our history would not come to an end. We might not even have to die as individuals. Hitler’s fate was sealed. Mussolini’s fate was sealed. As for the Japanese, they would be ground to powder. All the rest was merely the proper application of overwhelming force."
