In his Talking Points Memo tonight, Bill O'Reilly reacted to the vicious terror attack in Chattanooga, Tennessee.

O'Reilly warned about the potential fallout if ISIS is found to be connected to what happened today. 

“If ISIS is involved, even indirectly, all hell is gonna break loose in this country,” he stated. "For months, those savages have been encouraging people on the net to attack Americans."

"The Factor" host also blasted President Obama's ISIS strategy, stating that it has not been an "urgent campaign."

"I firmly believe that President Obama is making a major mistake in the tentative nature of his response to ISIS and I have said that many times," O'Reilly explained. 

He added that he hopes Obama's strategy will change, because "ISIS is a direct threat to all Americans."
