US foreign policy has not deviated from this same kind of practice one iota as Freedom of Information Act releases continue to confirm. We only find out long after the guilty administrations have moved on, except if leaked by Snowdens, Mannings, or Winners sooner.

In the US, the Truman and Eisenhower administrations are long out of power. Most Americans alive at the time this happened are dead now. Certainly the ones who were in power at the time.

That is not the same thing as systematically eradicating the institutions of power that allowed the atrocity to happen.

Do you want democracy and capitalism to be outlawed? What ideology?

I didn't say that. The question was, what's the difference between the relationships between the Nazis and the contemporary nation of Germany, and the Americans who committed crimes of imperialism in the 20th century and the contemporary nation of America. That's the difference.
