Syndicated columnist Charles Krauthammer said Friday on “Special Report with Bret Baier” that President Obama’s long-held promise to close Guantanamo Bay is a “preposterous idea” that has led to the release of prisoners from detention who threaten our national security.

“[His promise is] irrelevant, it's anachronistic, it's obsolete,” he said.

Krauthammer added the president’s rationale that the detention center has contributed to the rise of terror groups was simply false.

“The problem is not Guantanamo or holding them somewhere else,” he said, “It's that we're going to hold them in detention without trial forever, because the war is on and these guys are not convictable. So in Guantanamo or somewhere else, it won't change.”

Krauthammer argued that the president should give up his commitment to empty Guantanamo Bay, and instead keep “these bad people under our control.”

“We are hostages to a promise Obama made,” he said, adding, “He made a promise to withdraw from Iraq as well, and we saw how that turned out.”
