Russia is merely doing what we do when our interests are threatened.
Did they intervene when we invaded w/o provocation a country that touches their border? So why should we intervene here?
I've heard all the "what we should've done" and none of them would've made a bit of difference. We're pissing in the wind effing around in that part of the world. Another military invasion would've been a disaster. Arming moderates (which ones are they?) is only adding guns to the stockpile of American and Russian weaponry they have. Attacking Russia is obviously ridiculous.
Leaving 10,000 troops in Bagdad would've maybe slowed things by months, not years. This notion that keeping them there would've stymied the spill over from the Syrian civil war and the rise of post war terrorist groups is easy to scream but, conveniently, impossible to disprove and IMHO folly. So THAT was going to be the thing that finally brought peace to the region? lol
ISIL began on 9/11. Next year it'll be some new hip terrorist group with a different name but the same thing. It's a part of life now. I used to blame religion, but now I just blame people.
But Obama knows fools rush in (you know this now, too, thanks to Curious George and the Cakewalks)....ISIL is 30,000 strong in the occupied territories....there are ways to, ahem, somewhat contain that.
But the ideology is out there and these attacks are coming to the US - and there's nothing we can do to stop it except ramp up security and live with it just like every other country has for centuries.
