not for us ‘normal’ people.
But the Paperclip were useful to them, that’s why it can be seen as an understandable excuse.
The rest certainly not.

I’m tired of hearing about this as if it was the only one. It’s what they call a limited hangout.
Everyone knows it and it’s somewhat understandable from a pragmatic standpoint.
US/UK took effort to let them surrender to their western friends since the Russians would give the their deserved reward.
After which plenty somehow vanished.
And almost nobody knows about the ratlines, set up by the west to let all the other nazis escape.
Among them mass murderers like Klaus Barbie, Adolf Eichmann, Josef Mengele, Croatian Dictator Ante Pavelić, and Léon Degrelle.
And masses of low rank war criminals, the worst of the worst, including 1000’s of SS division Galizien from Ukraine.
Shipped to the UK and then got relocated with new names in Canada.
Their offspring still very active and with the same despicable ideology.
The Hunka incident is not a coincidence.

A huge amount of deaths are directly caused by US sanctions in numerous countries.
You should count those

Another thing we can accuse the US and their UK poodles of it’s only hanging a handful of nazis for show in their Nurenberg showtrials. (if that’s what you’re referring to)
They gave the vast majority of nazis all the help they needed escaping to S-America, Canada, etc…
Or simply forgave them and left them in high positions.
