By we, I’m assuming you mean the american military complex. Too echo others they didn’t stamp out the Nazis they hired them as “scientists” and higher ups in the intelligence agencies. And the ideology lives on around the world and is on the rise. The Taliban and Isis were essentially created by the CIA, u can read about it on Wikipedia. America isnt in western asia to stop the Taliban, America is there to extract resources. But even if America was in western Asia to stop the Taliban america did little to stop Nazi Germany they didn’t enter the war till close to the end and Soviet union had annexed the capital 3 days before the US military was there
