Except we didn't kill them wholesale. The United States pardoned or looked the other way for lesser Nazis and Imperialists in Japan to run their respective postwar governments. How do you think these countries functioned after the war? It's not like they systematically shot every remaining Nazi.

I don't think comparing state actions against other states is very useful or instructive when you're talking about non-state actors. We don't "wage war" against domestic political groups. That doesn't mean we shouldn't do anything, but I hope you realize that military action is an extreme response to what amounts to a relatively small (but worrying) group.

Whbat part of Islamists have waged terror that you did not understand. I am not advocating arresting Muslims for simply being Muslim, just as I am not advocating arresting neo nazis for being neo nazis. We don't want laws that are different for certain groups, or how rich someone is. That the law applies equally to everyone is something that is valuable to preserve. We don't want to go back to the old days where blacks were treated by the law as inferior. Suggesting you do this to any groups because you don't like them is a travesty of justice.

Actually, the US granted amnesty and asylum to a shit load of Nazis and brought them to the US.

Look up Operation Paperclip.
