I don't think everything that Obama has done has been bad, not by a long shot.
But what's the endgame in Syria, what was the endgame in Libya . . . the same for Iraq (Not Obama)?
Destroyed/destabilized countries don't pose a threat and easier to control (as long you control the right people)?? That's a serious game of, pardon the pun, Russian Roulette. Because only a dummy can't see what can be fermented in the rubble. This also really has nothing to do with Democracy. For me, Brzezinski's "Grand Chessboard" is the primer for all of this, control of Central Asia, thwarting the influence of Russia and China and their proxies of which Iraq, Syria and Iran are/were the biggest.
