This is the most comfortable period in human history. Just two generations ago, my family were peasants who didn't even have electricity! there's more at stake these days, and war offers more losses than winnings. No one wants to go off to a foreign country to fight individuals who have never done anything to you, even people in the military don't want a conflict. No one joins the army for glory anymore or for love of one's country, people join it because of the benefits. Everyone is after improving their own lives, no one gives a damn if country A shoots a toy that country B was playing with. The politician who gets this new mentality is the one who'll probably stay in office the longest. Trump seems to get it.
