I don't really disagree with anything else you say, but...
>When has a war with USA ever saved lives?
I don't know. I think there was a war of note which might have been around the 1940s?
It's fine to say that the costs of an interventionist foreign policy don't outweigh the benefits; I don't necessarily disagree with that. But it's absolutely inaccurate to say that the benefits don't exist. USA at the very least contributed a great deal to the European Theatre, and Imperial Japan was dethroned almost entirely due to their effort.
It turns out that all three of Italy, Germany, and Japan were successfully occupied and now have stable and democratic governments, as well.
