It wasn't until Barack Obama was in office and announcing the time table for his pull out of American combat troops that ISIS began to concentrate on filling that power vacuum in Iraq.
Bush beat Obama to announcing a time table for withdrawal. Bush set the timetable in stone with the SOFA when he surrendered to Maliki and Muqtada Al Sadr in December 2002. Iraq became a sovereign nation while Bush was in office. Obama could never undo that sovereignty. All US SOFA's require immunity for US military personnel from the courts and laws within the country in which they serve. Bush signed a deal with sovereign Iraq promising to have US troops out of cities in six months and completely gone in three years.
I can't believe you ever read the historical documents related to Iraq, so here are some pertinent parts:
U.S.-Iraq Status of Forces Agreement, 2008
Agreement Between the United States of America and the Republic of Iraq
On the Withdrawal of United States Forces from Iraq and the Organization
of Their Activities during Their Temporary Presence in Iraq
Recognizing the performance and increasing capacity of the Iraqi Security Forces, the assumption of full security responsibility by those Forces, and based upon the strong relationship between the Parties, an agreement on the following has been reached:
- All the United States Forces shall withdraw from all Iraqi territory no later than December 31, 2011.
- All United States combat forces shall withdraw from Iraqi cities, villages, and localities no later than the time at which Iraqi Security Forces assume full responsibility for security in an Iraqi province, provided that such withdrawal is completed no later than June 30, 2009.
- United States combat forces withdrawn pursuant to paragraph 2 above shall be stationed in the agreed facilities and areas outside cities, villages, and localities to be designated by the JMOCC before the date established in paragraph 2 above.
- The United States recognizes the sovereign right of the Government of Iraq to request the departure of the United States Forces from Iraq at any time. The Government of Iraq recognizes the sovereign right of the United States to withdraw the United States Forces from Iraq at any time.
- The Parties agree to establish mechanisms and arrangements to reduce the number of the United States Forces during the periods of time that have been determined, and they shall agree on the locations where the United States Forces will be present.
The Iraqis never intended to extend the immunity provided in the three year agreement that Bush signed his last full month in office. It was Bush's failure to negotiate at least a ten year deal with immunity that made the three year deal a fixed hard date that Sunni terrorists and Saddam's former military officers and fighters knew they could operate freely in Iraq's Sunni cities within five months of Obama's inauguration.
That's on Bush. Obama had no means to force sovereign Iraq to grant immunity to US Troops in 2012 and beyond. Bush locked Iraq's sovereign right to enforce Iraq's legal and political will on US Troops.
Bush's flimsy three year wimp out deal sealed Iraq's fate as Maliki used those three years to disenfranchise Sunnis and set up a crony ghost Shiite army that couldn't fight ISIS until Obama got them to fight their own fight the past 18 months.
