Dick Cheney and his daughter, Liz, were on “The Kelly File” tonight to discuss their scathing op-ed in the Wall Street Journal, entitled, “The Collapsing Obama Doctrine.”

In it, they wrote:

Rarely has a U.S. president been so wrong about so much at the expense of so many. Too many times to count, Mr. Obama has told us he is "ending" the wars in Iraq and Afghanistan—as though wishing made it so. His rhetoric has now come crashing into reality. Watching the black-clad ISIS jihadists take territory once secured by American blood is final proof, if any were needed, that America's enemies are not "decimated." They are emboldened and on the march.

Paul Waldman, of the Washington Post, countered the op-ed with his own, entitled “Maybe listening to Dick Cheney on Iraq isn’t a good idea.” He wrote, in part:

And now, as the cascade of misery and death and chaos he did so much to unleash rages anew, Cheney has the unadulterated gall to come before the country and tell us that it’s all someone else’s fault, and if we would only listen to him then we could keep America safe forever. How dumb would we have to be to listen?

Megyn Kelly asked the former vice president what he would say to people who suggest he helped cause the mess in Iraq.

“Obviously, I disagree. I think we went into Iraq for very good reasons,” Cheney said. Instead of negotiating a stay-behind agreement, Cheney said Obama “basically walked away from it.”

Liz said Obama is a dangerous president.

“I think that he is unique in terms of a president who is sitting in the Oval Office, who has made very clear that his desire is to weaken the nation.”

Cheney said that in the last four years, there has been a 58 percent increase in the number of jihadist groups around the world.
