Nazi Germans were not present after WW2? That’s a crazy thing to say when they were the ones who elected the Nazi party in the first place.
We should probably establish who we are talking about here more precisely. Are we talking about literal Nazis who kill people or are we talking about those who are angry at minorities and dislike Jews? Is it even everyone who voted Trump? If it’s the latter, you’re gonna find that you can’t just use force, the % is too large.
