On the contrary, the point is very arguable.
Germany's neighbors punished and humiliated that country with the harsh conditions set forth in the Treaty of Versailles. THAT, is what set Europe on the path to WWII, not America's participation in the First World War.
Hitler didn't declare war on the United States until after the Japanese bombed Pearl Harbor. He'd already been making war against his European neighbors for years, at that point.
Funny how the Blame America Firsters always twist history to make America the bad guy.
A little known factoid from history, America was carrying on a undeclared military action against the Japanese, before Pearl Harbor. We outfitted, and supplied planes, pilots and other personnel, to the Chinese. Our men actually bombed sovereign Japanese territory, flying planes with Chinese insignias, but make no mistake, they were American servicemen. The Flying Tigers, were war criminals, but since we won the war, and wrote the history, they are heroes. Chew on that a bit.
