Obama has failed playing the "Game of Thrones" in the Middle East. Obama has illegally interfered in the sovereignty Libya, Egypt, and Syria. Furthermore, Obama has two bad uncooperative puppets. Maliki in Iraq and Karzai in Afghanistan. Finally, Kerry, the US Secretary of State, failed miserably at attempting to negotiate a cease fire between Hamas and Israel in Gaza.
Obama's meddling in these countries has result in ongoing civil strife including a continued humanitarian disaster. Even the Washington Post finally acknowledged: "Libya crumbles as the United States looks the other way". More relevant to current events, the Post noted that "The Kurdish forces facing the Islamic State need help from the United States". Today, Obama finally announced limited aid and limited military assistance for the Kurds, Christians, Yazidis, and other ethnic/religious groups being marked for genocide by the Islamic State. "As The Washington Post's Loveday Morris reports, as many as 40,000 remain stranded on "the craggy peaks of Mount Sinjar," dying of hunger and thirst and devoid of much support from a faltering Iraqi government."
While Obama is finally getting around to countering the ISIS advances, it is also Obama who facilitated the rise of ISIS by supplying (illegal) covert aid to so-called rebels in Syria. ISIS having been one such group. Had Obama supported the Assad regime, even if it is considered deplorable, the rise of ISIS may never have occurred as the Assad regime may have been able to neutralize ISIS. By destabilizing Syria and weakening the Assad regime Obama made a strategic blunder.
It would be ludicrous to place all blame on Obama for the chaos in Middle East since there are many players involved in this "Game of Thrones". Nevertheless, Obama meddling in "Nation Building" and "King Making" make him partially responsible for endless war and the ongoing humanitarian disaster.
