Bill O'Reilly joined Fox and Friends this morning to give us his take on the latest developments in the Bowe Bergdahl prisoner swap controversy. A report by Fox News' James Rosen Thursday stated that Bergdahl converted to Islam at one point during his captivity and declared himself a "mujahid."

O'Reilly said he is not ready to call Bergdahl an enemy collaborator.

"Our sources cannot confirm that at all. It wouldn't be fair to the sergeant to make those charges," said O'Reilly, adding that "we do know he was a deserter."

Tune in tonight at 8/11p ET as Rosen joins O'Reilly to discuss his reporting.

O'Reilly believes people don't fully understand how bad the five Taliban leaders who were released from Guantanamo Bay really are.

"You don't exchange war criminals for a suspected deserter. That is not a good deal for this country on any level," said O'Reilly, noting that the former detainees should be tried in The Hague for war crimes committed while the Taliban was in power prior to 9/11.

O'Reilly likened the Taliban leaders to Nazis, recalling that they were responsible for beheadings of women for going to a dance, among many other crimes.

The Factor host believes President Obama "doesn't understand the groundswell against him" for making the deal, calling it a "victory" for the Taliban.

He said he has sympathy for the Bergdahl family and understands the concept of "leave no one behind," but reiterated that he still would not have made the deal.

"This is war. And people die. And more people will die from this exchange."

Watch the full interview above, including details on O'Reilly's newest book, Killing Patton.

In the clip below, you'll hear a different opinion on the Bergdahl swap from Geraldo Rivera, who believes the U.S. absolutely cannot waver from the promise of leaving no soldier behind. He argued that the five detainees would have been released anyway in a year when the war ends, and noted they had already been held for more than a decade without charge.

O'Reilly later called Rivera's take "insane," and the two will go back and forth, tonight at 8/11p ET on a must-see O'Reilly Factor.
