Don't sit there and pretend China and Russia, supporting Syria and Iran who in turn fund and militarize extremists across the middle east, had no part to play in the infinite proxy war. Not to mention Russia was the primary trading partner of Iraq under the rule of Saddam Hussein. While certainly the Bush Administration took advantage of the situation, the USA got roped into the war on terror by the 9/11 attacks orchestrated by a group of extremists from Saudi Arabia and Pakistan holding a suspicious number of AK47s popularized in the USSR, and under Obama and with help from NATO members as well as the Saudis the region was stabilizing and demilitarizing very quickly with both stronger borders and less US Troop presence.
