President Obama called for a credible investigation into Malaysia Airlines Flight 17 that was shot down over Ukraine on Thursday killing all 298 people on board. He called on Ukraine, Russia and the separatists to put an end to the fighting.

“Evidence indicates that the plane was shot down by a surface-to-air missile that was launched from an area that is controlled by Russian-backed separatists inside of Ukraine," President Obama said.

Tonight on The Kelly File, Lt. Col. Oliver North said the difference between President Reagan’s reaction to a downed Korean Airlines flight by the Soviet Union and President Obama’s reaction is that Reagan was in the business of “rebuilding” America’s defenses.

“We all know now that Barack Obama is disabling America’s defenses. We are unilaterally disarming and everybody knows it,” North said.

He told Megyn Kelly that Russian President Vladimir Putin knows the United States will not act.

North said he was told that one of the black boxes from the plane has not yet been found.

“If that’s true, there ought to be a NATO […] operation to recover that black box if it’s still on the ground in Ukraine. They ought to do this quickly so that information is not tampered with,” he said.
