Real shame it didn't take that long after those soldiers of WW2 died out to forget all the lessons taught.
If there is some parallel dimension where after WW2 we went something much closer to isolationism, perhaps with some baseline effort to balance against the USSR, the US and the world alike would be a vastly better place today. And most notably this whole issue continues on to this very day. Our foreign policy is completely self defeating.
