Socrates, your answer is somewhat of a surprise because you have rewritten history or ignored it...perhaps both.
The LAWLESSNESS of the dangerous Cheney/Bush administration is what caused "the rise of ISIS (now ISIL) in Iraq and Syria"! Prior to the ILLEGAL 2003 invasion of Iraq, a nation that had never once attacked the United States and that had no involvement whatsoever in 9/11---something both GW and Cheney knew prior to the ILLEGAL invasion---Sunnis had ruled in Iraq for 13 centuries, and there was relative stability because of that Sunni rule. The Cheney/Bush administration, like the Reagan/Bush and Bush/Quayle administrations, had kept the right-leaning PR firm Hill & Knowlton on retainer, and assigned them the task (as uncovered by "60 Minutes") of falsely painting Saddam Hussein as a "villain" in the minds of the American people to "justify" first the Gulf (wag-the-dog) lied-based "War" during an election year and then from 2001 through to 2008 for the purpose of setting up "an excuse the public would buy" (a quote from their then-Treasury Secretary Paul O'Neill) to ILLEGALLY invade oil-rich Iraq to gain a Cheney-lusted foothold in the oil-rich Middle East.
George Bush DID CREATE the conditions that created the furies of Abu-Bakr Baghdadi, a Bush/Cheney detainee in their TORTURE CHAMBER detention centers, with the 2003 ILLEGAL invasion and the subsequent Cheney/Bush-ordered TORTURE of Muslim detainees, most of whom had not committed any crimes. Baghdadi witnessed this and had plenty of time as a detainee to NETWORK with other detainees...and voila! The creation of the Islamic Sunnis in Iraq and Syria (ISIS) was born.
GW claimed first that he was "tired of hearing about al-Qaeda" when NSA Director Richard Clarke tried to warn him prior to the 9/11 attacks---the attacks that both he and Cheney decided to allow as that "excuse the public would buy" (but first letting their two influential friends and campaign donors Frank Lowy and Larry Silverstein first get picked to have granted to them the lucrative 99-year leases of the WTC through former GOP Federal Finance Committee Chairman turned Chairman of the NY and NJ Port Authority Lewis M. Eisenberg---for the LOWEST BID of only $3.2 BILLION---just six weeks prior to the 9/11 attacks. The Bush family-controlled reinsurers of the WTC (including Securacom, as discovered by Larry Flynt in "Sex, Lies & Politics: The Naked Truth" and Industrial Risk Managers did the payouts: Wirt Walker I maternal uncle Chairman of the Board, uncle Jonathan the CEO of one Texas-based reinsurer, Wirt Walker III maternal Cousin and GW brother Marvin Bush on the Boards). Lots and lots of $millions$ to be had! This is GW Bush "dealing" with impending attacks by al-Qaeda.
The Arab Spring civil rebellion in Syria matched in intensity the Arab Spring citizen-led rebellion in Libya against their dictator Moammar Khaddafy (Qadafi), even thought he Syrian rebellion came later. In Syria, however, the newly formed al-Qaeda in Iraq (ISIS at the time) and the known anti-Israel terrorist group al-Nusra Front, also affiliated with al-Qaeda, immediately infiltrated into Syria with the intention overthrowing Bashir al-Assad to spread al-Qaeda influence in the Middle East. GW would have colluded with his no-bid Defense contractors and weapons manufacturers (as did Cheney through the CIA-controlled-BCCI scandal) to send unlimited and unmonitored lethal weapons into Syria without any concern as to whether these lethal weapons would fall into the wrong anti-U.S., anti-U.S.-allies hands, enabling the terrorist groups to seize control of Syria in the same manner that ISIS-turned-ISIL ruthlessly seized territory as its influences spread.
Bush/Cheney would also have paid NO ATTENTION to the rift that occurred between al-Qaeda's leader Aymann Zawahiri and the then-ISIS leader Baghdadi, with Zawahiri furiously ordering Baghdadi out of Syria, telling him to confine his group to Iraq...and then the open DEFIANCE of Baghdadi, who changed his group name in 2014 to ISIL (Islamic State in Iraq and the Levant), targeting most of the nations in the Middle East plus both Palestine and Israel, thus becoming far more dangerous. Would GW Bush or Cheney have been able to forge a SIXTY NATION COALITION that included Arab nations to handle the expense and to join in on the U.S.-led military airstrikes? I seriously doubt it. President Obama has done everything right without yet having to put more of our combat troops on the ground.
Socrates: The 2008 Status of Forces Agreement (SOFA) signed by GW and the Cheney-picked al-Maliki set the complete-withdrawal date for December 2011 of all American troops, and Maliki was viciously militant from the beginning, prejudiced against all Sunnis and excluding Sunnis from the army, the police, or the government, all done prior to President Obama taking office and prior to the release if ISIS (now ISIL) leader Baghdadi from the Bush/Cheney detention!
