What you seem to be saying is that you don't really like the outcome, because Nazi affiliation shouldn't have been ignored in Operation Paperclip. That's fair enough, and I think there are a lot of people who would agree. But that's not really what this is about - nobody is objecting to the idea that US intervention could have been better - they (and I include myself) - are objecting to the idea that it was negative. That you reply in this way, which avoids the fundamental question of whether it was overall positive or negative, implies to me either that you realise there's a problem with your original statement, or that you think any intervention that isn't perfect is in fact negative.
