Trump: I'm the Only Candidate That Won't Be Controlled by Donors

'Outnumbered' Reacts After Obama Says We're Hitting ISIS 'Harder Than Ever'

President Obama now knows that his decision to completely withdraw U.S. troops from Iraq was a big mistake, Charles Krauthammer said on "Special Report."

Krauthammer pointed out that the Pentagon is reportedly now pushing to keep Bagram Airfield in Afghanistan open beyond 2017.

It comes after Obama revised his withdrawal timetable, agreeing in October to keep a 9,800-strong force through most of 2016 and then draw down to 5,500. 

Krauthammer argued that President Obama now realizes that leaving some U.S. air bases in Iraq "would have made a decisive difference in the rise of ISIS."

"I think Obama understands that was a terrible mistake [that] he doesn't want to repeat in Afghanistan," said Krauthammer.

Meantime, a new CNN poll shows that 64% of Americans disapprove of how Obama is handling ISIS, compared to 33% approval. 

Krauthammer pointed out that the administration recently boasted of 600 airstrikes since July against ISIS targets. 

"Do the math. That's an average of three a day. This isn't exactly an air campaign," he said.
