No one, as far as I can tell, ever has accused Michael Hayden of being a squishy moderate or liberal.

The retired Air Force general led the Central Intelligence Agency during the George W. Bush presidential administration. He knows foreign policy as well as anyone.

Gen. Hayden thinks very little of the credentials of two of the leading Republicans running for president. Imagine that.

Hayden has ripped Donald Trump and Ted Cruz for differing reasons, but the common thread lies in their misunderstanding of what it takes to conduct foreign policy.

The general was critical of Trump’s pledge to bring back waterboarding as an interrogation technique to use on terror suspects.

Trump said: “Believe me, it works. And you know what? If it doesn’t work, they deserve it anyway, for what they’re doing. It works.”

Hayden’s response is that the United States doesn’t use certain techniques on suspects because they “deserve it.” He calls Trump’s view of waterboarding a gross misunderstanding of how and why U.S. employ certain tactics against individuals suspected of doing harm.

And what about Sen. Ted Cruz’s pledge to “carpet bomb” Islamic State targets? Hayden calls it “inhumane” and not in keeping with U.S. principles. Cruz once vowed to see if he could get “sand to glow in the dark.”

These tough-talk pledges from individuals seeking the presidency need to be revealed for what they are: reckless bravado aimed at firing up people’s anger and fear.

Gen. Hayden has been at the center of the very issues that candidates such as Trump and Cruz use as political rally applause lines.
