Bill O'Reilly's own guest mocks his plan to defeat the Islamic State

Bill O'Reilly thinks he has a plan to defeat the Islamic State militants: A 25,000-person mercenary army.

"Elite fighters who would be well-paid, well-trained to defeat terrorists all over the world," the Fox News host said on Monday's "O'Reilly Factor." "Here's how it would work: The fighters would be recruited by America and trained in the USA by our Special Forces."

The U.S., O'Reilly said, would be in charge of who makes the cut and how they are deployed and would provide "logistical support."

O'Reilly said he is "tired of the phony rhetoric" coming out of the Obama administration about having no U.S. "boots on the ground" in Iraq and Syria.

"Even if the USA trains Syrian moderates and gives them weapons, they will not — not — be able to defeat the terrorists," he said.

The English-speaking, Kurdistan-based force would be called "the Anti-Terror Army" and paid for by the coalition of countries the Obama administration is trying to put together.

"That means that all countries that want intelligence and protection from the USA and NATO would have to chip in," he said. "If they don't pay, they get no help."

O'Reilly's war plan was immediately mocked by many, including his own guest, U.S. Naval War College professor Tom Nichols.

"This is a terrible idea. It's a terrible idea not just as a practical matter but as a moral matter," Nichols said. "It's a morally corrosive idea to try to outsource our national security. This is something Americans are going to have to do for themselves. This is not something we're going to solve by creating an army of Marvel 'Avengers' or 'Guardians of the Galaxy.'"

"We're not talking about 'Expendables 8' here," the Fox News host countered. "We're talking about a highly trained, disciplined force."

O'Reilly dismissed the criticism, doubling down on his mercenary plan on "CBS This Morning" Tuesday.

"It's going to happen," he said. "This anti-terror army is going to happen."
