Iraq crisis: Is it time for al-Maliki to step down?

(CNN) – The U.S. handed him the keys to Iraq when it pulled out combat troops in 2011, and asked him not to scratch it.

But Iraqi Prime Minister Nouri al-Maliki has since lost control of a wide swath of his country.

And now some, like the chairwoman of the Senate intelligence committee Dianne Feinstein, are wondering aloud whether it's time for him to hit the bricks.

"It seems to me that Maliki has to be convinced that it is in the greater interest of his country to retire and for this newly elected government to put together a new government," said Feinstein.

The Woodrow Wilson Center's Robin Wright and Dartmouth's Daniel Benjamin, former the principal adviser to Secretary of State Hillary Clinton on counterterrorism, discuss.
