Following terror attacks in Canada and New York City and amid waves of threats on the Internet, The Department of Homeland Security has stepped up security at more than 9,500 federal buildings across the country as a "precautionary step."

It has been reported that ISIS and other terror groups are hoping to use social media to capture the imagination of self-radicalized individuals or lone wolves.

Pete Hegseth warned on "Outnumbered" today that if the U.S. is not willing to defeat the enemy on the battlefield, then this could become the new normal.

Peters on New ISIS Massacre: 'Obama Can't Make Hard Decisions'

Hegseth is among many who are questioning the Obama administration's plan for defeating ISIS, believing that the U.S.-led campaign of airstrikes needs to be supported by U.S. troops on the ground.

Sen. John McCain said yesterday, "ISIS is winning. We’re losing. And one of the reasons is because we're not able to identify targets."

"Only this president could warn ISIS a week ahead, so that they could all get out of the buildings on time that we saw explode … so, yes, we’re going to have to have boots on the ground. And the more we delay, the heavier the price will be.”

Hegseth, as he recently explained in a piece on, said that the Obama administration is incapable of calling the enemy by name, let alone doing what is necessary to destroy it.

“This president is very good at fighting faceless enemies: the weather, health, disease. But when it comes to an enemy with a face, a jihadist - a militant who seeks to kill us - whether it’s a lone wolf or a soldier, they don’t know how to handle it.”
