If anyone can be blamed for the current crisis it is al-Maliki for his persecution of the Sunnis since our troops left.
Are you drawing on a specific source for your claims of his persecution of Sunnis? Can you provide me with a link to one that you believe adequately represents that claim?
There are multiple references to his actions since 2009. Here's a couple.

Thank you. While I am not a fan of al-Maliki, I am a fan of the truth, and it appears that your links undermine your claims rather than supporting them.

The authoritarian tendencies of Prime Minister Nuri Kamal al-Maliki of Iraq are well known. But the arrest of more than 600 Iraqis whom the government describes as suspected former members of Saddam Husseins Baath Party and army is particularly cynical and reckless.
He arrested members of the banned Baath Party. The Baath Party's current leader, Ibrahim al-Nouri (who was Saddam's Vice President), declared war on ISIS recently due to their inhumane treatment of Christians. Additionally, ISIS is a Sunni extremist organization. Arresting members of the party that went on to fight a Sunni extremist organization hardly seems like it would damaging al-Maliki's street cred.
In Iraq, a Sunni revolt raises specter of civil war - The Washington Post
In the western Iraqi province of Anbar, Sunnis are in open revolt against the Shiite-dominated government of Prime Minister Nouri al-Maliki. Militants affiliated with al-Qaeda have taken advantage of the turmoil to raise their flag over areas from which they had been driven out by American troops, including the powerfully symbolic city of Fallujah, where U.S. forces fought their bloodiest battle since the Vietnam War.
On Monday, Maliki urged the people of Fallujah to expel al-Qaeda-*affiliated militants to avert a full-on attack, echoing calls made by U.S. forces a decade ago when they warned residents to leave the city or suffer the consequences.
Here, al-Maliki fights the Sunni organization al-Qaeda, or a splinter group affiliated with them.
I just don't see how these articles prove that al-Maliki is guilty of "persecution of the Sunnis since our troops left."
