Charles Krauthammer tonight weighed in on Fox News poll numbers on ISIS, as well as a 2007 clip in which then-Sen. Barack Obama remarked on the Muslim world.

In 2007, Obama told New Hampshire Public Radio, “I truly believe that the day I’m inaugurated, not only does the country look at itself differently, but the world looks at America differently. If I’m reaching out to the Muslim world, they understand that I’ve lived in a Muslim country, and I may be a Christian, but I also understand their point of view. Then, I think that the world will have confidence that I am listening to them … That will ultimately make us safer.”

Krauthammer blasted the statements as “preposterous.”

“That is a toxic combination of naivety on the one hand and grandiosity on the other hand,” he said, slamming the president for going around saying that the U.S. will finally respect the Muslim world – as if it hadn’t before.

Now, Krauthammer said, “Everywhere you look in the Muslim world […] you have got a deterioration of the U.S. position.”

Krauthammer told Megyn Kelly that Obama chose weakness, withdrawal and decline because he thought it would appease U.S. enemies, but it had the opposite effect.

Krauthammer also weighed in on a Fox News poll which found that a majority of Americans would support ground troops against ISIS if airstrikes aren’t enough. The poll found that 78 percent support airstrikes, but 57 percent say that defeating ISIS will take ground troops. If airstrikes aren’t enough, 52 percent would favor ground troops.

An overwhelming 64 percent of respondents said the U.S. has no ISIS strategy.

“Americans are exactly right – airpower will not be enough, Obama does not have a strategy,” Krauthammer said. However, he said the number of people who support ground troops is ephemeral and would change if we actually put ground troops in Syria and Iraq.

He said that the current poll number is one that you get “when America has not as of yet sustained so much as a sprained ankle in this campaign.”

“This is very pristine conditions right now, and that could change overnight,” he said.

Krauthammer also told Kelly that he doesn’t think Iran will allow Baghdad to fall to ISIS.

“To take and hold Baghdad would be something different. That would trigger U.S. ground troops, but I don’t think we’ll get there.”
