Fox News strategic analyst Lt. Col. Ralph Peters and Lt. Col. Tony Shaffer, senior fellow at the London Center for Policy Research, discussed the deadly Chattanooga, Tennessee shooting on "The O'Reilly Factor" tonight.

Peters said that he has no doubt in his mind that the shooting will be traced to ISIS.

"As long as the Islamic State caliphate exists in the Middle East as inspiration to the would-be jihadis, there are going to be more lone wolves and larger attacks here," Peters stated.

He added that we have to stop playing defense and make the terrorists afraid. 

"We're lying to ourselves about the nature of the problem still," Peters explained. "We are not facing a political ideology gone wrong. We are facing religious fanaticism ... Until we go on the offensive, the terror will not end."

Shaffer agreed with Peters and said the Chattanooga shooting was an act of terror. He suggested that a number of things need to be done in order to combat ISIS. 

"We've got to show that we're in this to win it," Shaffer said. "We've got to go into the region to take out the leadership with complete impunity."

Peters added that "terrorists don't have rights" and to "get over it."

"We are in a war and we're pretending we're in a debate," he stated.
