@capnthommoDepends whose holding the gun. Hitler shot himself when overwhelming force of arms from all sides had captured most of Germany and the bunker was all he had left. The Italians realised a couple of years previous they were on the wrong side of history and turned on their own leaders. I don't see any one invading the US to defeat Trump so it looks like you will have to do it yourselves. Or hope he goes quietly in 28 and someone sensible takes charge. Good luck.
