Charles Krauthammer said Friday on "Special Report with Bret Baier" he is "not impressed" by President Obama's announcement that he is forming an international coalition to take on the Islamic State militant group, claiming the coalition is "theoretical at best" until Obama has a strategy.

Krauthammer, a syndicated columnist and a Fox News contributor, said in his opinion the biggest news to come out of this week’s NATO meeting was President Obama was finally able to tell the world his objective was the destruction of the group. 

"I think the major event that came out of the conference in Wales, the NATO summit in Wales, is that it had nothing to do with NATO, it had to do with the inside of Obama’s head," Krauthammer said. "After three attempts he was finally able to tell the world what his objective is, the destruction of ISIS, and that he’s working on a plan."

However, Krauthammer said he was "not impressed" by the president's announcement he intends to form a coalition to take on the group.

"The important thing here is that Obama has a strategy," he said. "When he talks about a coalition we need to know: what are these other countries going to do? He hasn’t told us and until he does that coalition is theoretical at best."
