Does Obama's 'no boots on the ground' fail to address Hagel's call to alarm about ISIS?

(CNN) – Secretary of Defense Chuck Hagel said Thursday that the militant group responsible for beheading an American journalist "beyond just a terrorist group."

"They marry ideology, a sophistication of strategic and tactical military prowess. They are tremendously well-funded. Oh, this is beyond anything that we've seen. So we must prepare for everything," Hagel said Thursday.

But then the secretary of defense went on to say there will be no mission creep, and the operation in Iraq will continue to be President Obama's limited mission of airstrikes in Iraq.
