I thought it was common knowledge that the US (esp. industry) for years collaborated with Nazi Germany? Near the time they entered the war, the US propaganda machine worked hard to erase the fact. They were successful, especially after winning the war. This is not meant as calling-out the US in particular. The nazis and soviets had large scale propaganda, too. It goes without saying that the latter still do, just like the US. There is an abundance of examples, but one that I personally really like is https://en.wikipedia.org/wiki/Education_for_Death https://en.wikipedia.org/wiki/Education_for_Death .
