Geopolitically speaking, this election isn't about Trump vs. Hillary. It's about whether you want US foreign policy to be directed by Americans (however crooked one of them might be) or by the Russians (however strong they might make their voters feel). Given that choice, I'd suggest voting for the crook: it's important.
You're exactly right. But, I'm frankly tired of the proxy wars and the droning of brown people in sand for the control of oil and gas and, of course, pipelines. Not to mention the regime-change agenda over there that started during the W. Bush administration.
So I don't want Hillary in charge to further that agenda and escalate things over there. The only good it does for anybody is to line the pockets of multinational corporations (and, of course, the politicians that help them gain access to resource they can exploit). And those guys don't give two figs about America or Americans. They don't even bother paying US taxes on all those gains - most of it they stick in some foreign tax haven somewhere so they can get to it when they're ready to retire to one of their tropical villas where all the local officials are already owned (by them).
So, yea, if you're all concerned about continuing to squeeze the middle class of their ever-dwindling wages so you can spend it fighting foreign wars to prop up the globalists and the bankers, by all means support Hillary as your candidate. For me, I'd rather leave them to their own devices. We'd be better off working in the weapons factories and selling bombs and ammo to the ones left there fighting over some desert. We've got enough of our own gas and oil to do just fine until they're done bombing each other to oblivion and have established the caliphate in the EU.
