Ha, ha, ha...of course. You won't say. Naturally, because that would destroy your narrative of being pure and good like Bernie Sanders (a Judas goat for the corporate Democrats as you know of course) told everyone. Riddle me this: would you be able to afford all of those fantastically expensive social programs without a distant foreign country paying a ruinous amount from their own citizens' pockets for your defense? Military spending is incredibly costly, and you've got an idiot to do it for you. European politicians were quite open about refusing to carry their fair share of the load, saying clearly that if they spent the required amount on defense they would be voted out of office by their own voters. The vast majority of Europe haven't paid their fair share for decades.

Do we really have something to lose as Americans if we pull back our external activity? The Cold War is over, and it seems the more fingers we have in pies like NATO, the Middle Eastern countries, and so forth, the more problems we create.

Let Europe defend Europe. They are not incapable nascent and fragile democracies anymore. Giving Europe its self-determination is the mark of a true ally. Granted, it might mean compromises to their various social welfare states or tax increases because military might is expensive, but it is their decision to make.
