Kind of a click bait-y title. They claim there is no afterlife besides heaven, Hitler is dead, therefore Hitler went to heaven. In their mythology, hell doesn't exist.
They're also a raging antisemite who thinks the Nazis did nothing wrong and fascism is the only way to save America. So in a roundabout way the title isn't that wrong.
Damn straight! Countries should be able to invade and annex other countries without fear of reprisal! What's this world coming to?
