Bill Clinton doesn't approve of the persistent criticism Dick Cheney has lobbed against the Obama's administration's policies when it comes to Iraq.

"Mr. Cheney has been incredibly adroit for the last six years or so attacking the administration for not doing an adequate job of cleaning up the mess that he made," Clinton told NBC News "Meet The Press" host David Gregory. "And I think it's unseemly. And I give President Bush, by the way, a lot of credit for trying to stay out of this debate and letting other people work through it."

Clinton argued that if the U.S. had not gone to war with Iraq during the Bush administration, the chaotic sectarian violence that has plagued Iraq in recent weeks would not be happening.

"Well, it might be happening in Syria, but what happened in Syria wouldn't have happened in Iraq. Iraq would not have been, in effect, drastically altered, as it has been," said the former president. 

Gregory interviewed Clinton and the 2014 Clinton Global Initiative America meeting in Denver this week.
