Is that good reason to circumvent democracy?
"We hate commies, lets make decisions without the publics consent!"
I don't think it was a case of hating communists more than Nazis at all.
Many people, myself included, did not "hate"
the Russian people, nor did we "hate"
the German people.
We did hate the core Nazis who set the agenda and directed the attempted genocide of the Jewish people.
Many Germans were members of the party simply because it was the only way to get ahead in their profession. Maybe they were morally weak to do that, but who among us would know how we would act under similar conditions of ambition and patriotism to the
Fatherland.
But, the big difference between the Nazis (ex- or otherwise) after the war was that Communist Russia was seen as a threat and Germans, Nazi or otherwise, were not seen as any threat to national security.
Maybe the USA went too far in many areas. I think that they did with McCarthyism and its attacks on Afro-Americans seeking no more than to better their lot, eg
Paul Robeson and many from Hollywood. Some of these did have Communist leanings, but it was all handled so ham-fistedly!
But for a 15-year-old kid like yourself to be so critical of so much from so far back is a bit immature, though the extreme anti-Nazi feelings of anyone with connections with Israel is understandable.
So, for me the bottom line is simply that
the USA did not regard Germans, even Nazis, as any sort of a threat, but rightly or wrongly, they did regard Communist Russia as a threat to national security.
