What's next for Iraq?

It's been 10 years since the start of the U.S. war in Iraq. American troops are gone, but there's still violence in the country -- as Sunni insurgents launch frequent attacks on the Shiite-led government.

On Tuesday, four people were killed including an anti Al-Qaeda militiaman in Western Baghdad. Police say drive-by shooters sprayed his car with bullets.

Col. Douglas Macgregor, executive vice president of the Burke-Macgregor Group, discussed the progress made in Iraq with Capital Insider.
