Today, President Obama announced a plan of action in Iraq that includes sending up to 300 military advisers to assist the Iraqi military. He stressed that American forces will not be returning to combat in Iraq.

After the White House briefing, Republican Senator Marco Rubio (FL) criticized the president for announcing to the world what he will not do, even if he has concluded that boots on the ground is not the right approach.

On Special Report, Charles Krauthammer agreed with Sen. Rubio, saying it’s “always a mistake” to announce that something is off the table.

“I can assure you that if there is a Tet Offensive-like assault on the embassy in the Green Zone, there will be combat troops on the ground, otherwise we’re going to have Benghazi squared.”

Juan Williams argued that Republicans have been pressing President Obama to give the American public a strategy. “Part of what you’re going to do is what you’re not going to do.”

“No, it’s not,” Bret Baier pushed back. “What if somebody goes after one of these brigades? What happens?”

Williams responded, “We’re not speculating. We’re talking about what we’re doing right now.”

Krauthammer pointed out that it is speculation to say we’re not going to send combat troops to Iraq. He maintained, “You leave it ambiguous. Let the other guy stay up at night worrying about it.”
