Lt. Col. Ralph Peters joined Greg Gutfeld on "The O'Reilly Factor" tonight to react to comments made by Defense Secretary Chuck Hagel and President Obama in the wake of ISIS brutally executing American journalist James Foley.

These comments included the controversial disclosure of details of U.S. special forces attempting to rescue hostages in Syria earlier this summer.

Peters said the release of those details by the administration was shameful and could only be effective as weak political cover.

"You just don't do it," he said, adding that the release of details is disgraceful and murderous because it potentially endangers not only our soldiers for future raids but also the hostages that are still being held by ISIS, since we advertised that we received key intelligence from released hostages.

"You think the Islamic state is going to release more hostages? We signed their death warrants!"
