This looks to me like a well-intended sabotage by people within who do actually care:
The Guardian's Martin Chulov interviewed a senior leader of ISIS. According to the ISIS leader, the US military detention in Iraq was pivotal in the making of ISIS for it gave them 1) perfect safety and 2) an "invaluable" way of networking, planning and socializing. (This might be the best compliment ever said by someone about a prison):
"HERE, WE WERE NOT ONLY SAFE, BUT WE WERE ONLY A FEW HUNDRED METERS AWAY FROM THE ENTIRE AL-QAEDA LEADERSHIP."
In other words, the whole leadership of al Qaeda in Iraq, later-to-be ISIS, was there in US detention ... only to be released and to wage war on Syria and Iraq. (If I count well the release already came under Obama's watch)
According to Abu Ahmed, the interviewed ISIS leader, al-Baghdadi, the commander of the ISIS, who, like the rest of the al Qaeda leadership, was detained in one place with the privilege to associate with each other, "managed to trick the US Army into thinking he was a peacemaker and ... 'he was respected very much by the US army,;" Abu Ahmed said.
Baghdadi, as a US prisoner, could, '"f he wanted, visit people in another [prison]."
"If there was no American prison in Iraq, there would be no IS now."
US Bucca military prison "was a factory" that produced ISIS: "It made us all."
Who could say that of a prison, not to mention a US military prison and under the War on Terror?
The US detention was then really al Qaeda's "organizing space." It "allowed them to unify under the name al-Qaeda in Iraq (AQI), led at the time by Abu Musab al-Zarqawi."
"We could never have all got together like this in Baghdad, or anywhere else."
This was exclusive to the system under which they were kept.
"Here, we were not only safe, but we were only a few hundred meters away from the entire al-Qaeda leadership."
"[The] network [of ISIS was] organized partially out of US-run detention centers [which played a key role in that."
The Iraqi government, Chulov reports, estimates that "17 of the 25 most important Islamic State leaders running the war in Iraq and Syria spent time in US prisons between 2004 and 2011."
Without the invasion of Iraq and US detention/gathering of the whole al Qaeda leadership under one roof "ISIS as we know it wouldn't exist."
