Such a strategy, Wicker said, would involve weakening the group's financial network and working with local armies to dismantle ISIS.


"[W]e can stop ISIS with minimal ground troops if we engage and assist the Iraqi, Kurdish, and the Free Syrian armies," Wicker said. 

The Mississippi Republican said the Obama administration has, so far, not done enough to combat ISIS.

"Instead of a bold strategy to defeat ISIS, the United States has so far pursued a modest deployment of military advisers and limited airstrikes, which are insufficient to overthrow this organized, formidable and sophisticated force," Wicker said.

Wicker pointed to statements from administration officials suggesting that ISIS poses a serious security threat, such as Defense Secretary Chuck Hagel's statement that the group is "an imminent threat to every interest we have, whether it's in Iraq or anywhere else."

"If these statements are true, then Americans are right to question why President Obama has only issued half-measures in response," Wicker said.
