That's as pathetic an excuse as "We were only following orders."
I was born in 11947. Lived through air raid drills in school, along with being told every day we were going to be attacked. That propaganda was no different than the shit they told everybody about Covid, and the excuses they are using to send billions of dollars to Ukraine. Guess what? We didn't win the war against communism, or fascism despite using Nazi scientists and war criminals against our enemies, because both isms are alive, and well, and thriving in this country today. And last thing I knew, despite all the fear of the past, Russia still hasn't dropped a nuclear bomb on us, but with the bullshit going on in Ukraine, I couldn't blame them if they did.
Our national survival was at stake. In WWII we made deals with totalitarian Communists and with the Mafia. We did horrible things such as obliterating entire cities - civilians be damned. War isn't pretty and you don't get to just deal with choirboys when conducting foreign policy. Sometimes you have to do some shitty awful things like employing some Nazis, backing some 3rd world tyrants, etc. Playing Pollyanna is not going to result in a better world. It will result in a worse one. The Commies never hesitated to do awful things and had they won, the world would have been much worse off.
You want to create a moral equivalence between the USA and the Communists, never mind the Nazis. We part ways on this.
We didn’t starve millions of people to death and imprison millions of others for no reason other than to work them to death.
We didn’t murder tens or hundreds of millions of our own citizens like they did.
We aren’t the same. Not even close. It isn’t to say we aren’t going in that direction, because we are.
But we haven’t been them. And the Communists, Vietnamese, Chinese, Germans, Soviets, Cubans, and all the rest have freely murdered and oppressed both their countries and other countries.
I don’t buy into your moral equivalency with your assertion that the Soviets or the Chinese Communists were and are no threat. I lived through those times too.
Just because evil survives doesn’t mean you don’t fight against it as you assert we should not have.
