Well I was trying to be nice but yea. In WWIII Mexico would likly be left untouched. But than you would have no law, no supply chain, no nothing. So crime and food/water security is your main concern if your in Mexico.
And for the first time in history they will refuse to cross the border into the US .
I wouldn't want to live in Europe right now. Unless I had a kickass bunker in the mountains with plenty of food stored and running around.
