Chairman of the Joint Chiefs of Staff Gen. Martin Dempsey said Sunday that he will not recommend airstrikes against ISIS in Syria because there is no sign that the terror group is engaged in "active plotting" against the U.S. homeland.

Pentagon Press Secretary Rear Adm. John Kirby joined Martha MacCallum on “America’s Newsroom” today discuss whether or not ISIS militants pose a direct threat to the U.S.

Kirby said ISIS has the numbers, resources and leadership to pose a significant threat regionally, but not globally at this point.

The foreign fighters in their ranks who can travel abroad freely, however, make the danger in the U.S. more immediate. 

"While the general feeling is they are not capable of a 9/11-like attack on the homeland right now, they certainly could, through the use of foreign fighters, impact Western targets, including American targets, if they so choose," Kirby said.

He said the Pentagon is working diligently on preventing any such attack, including supporting Iraqi and Kurdish forces to oppose ISIS, in addition to the air campaign against the terrorists in Iraq.

Kirby added that international partners are coming together to combat this challenge and give humanitarian aid to those ISIS displaces.

Other neighboring countries, such as Jordan and Turkey, are beginning to see how great a threat the Islamic State poses, according to Kirby.

Asked if airstrikes could be used against ISIS in Syria in the future, Kirby stated, "We don't telegraph our punches here at the Pentagon. Our job is to be prepared and ready across the whole spectrum."
