From the Middle East, Syria, N. Korea and the Crimea, Obama was a total failure.
He alienated our strongest ally in the Middle East (Israel). Allowed Russia to take over the Crimea. Didn't do shit with N. Korea. Created a home for ISIS in Libya. And allowed the Russians and Iran entry into Syria (as well as punking out when Assad used chemical weapons on his own people).
He was a total idiot when it came to foreign policy.
