@thelinuxEXP it does affect a lot.
Without entering the interior US matters, I would say that this election could mark a point of the historical sinusoid of american foreign poltics. From time to time, they move outside, then they go back inside. It happened several times in last two centuries. If Trump will disengage NATO focusing in internal or Asia/Pacific matters, then Europe will start to re-arm itself. And every time that Europe started to re-arm itself, it ended up in bloodwash.
