In an interview on CBS's "Face the Nation," Sen. Lindsey Graham (R-SC) warned that the U.S. could soon see a "Paris on steroids" terror attack if ISIS is not defeated.

"Every day that goes by, we have got more terrorist organizations with more capability to strike the homeland than any time since 9/11. You got AQAP in Yemen. But ISIL's presence in Syria and Iraq, they're very rich. Foreign fighters flow with passports that can penetrate the United States and our Western allies," Graham said.

"So, you will see a Paris on steroids here pretty soon if you don't disrupt this organization and take the fight to them on the ground."

Graham said that it will take around 10,000 U.S. troops on the ground, aligned with Arab armies, to actually take back territory from ISIS.

On "America's Newsroom" today, Pete Hegseth agreed with Sen. Graham that to defeat ISIS, the U.S. has to lead, and we can't do that from inside our military bases.

"What we would want to do is very strategically and precisely position [U.S. troops] alongside indigenous forces who do the mass of the fighting," Hegseth said. "Absent that component, it's just not serious to talk about rolling back ISIS."

"You've got to build a comprehensive, strategic approach, and that's what I think Lindsey Graham is failing to see from this White House, what I'm failing to see from this White House. They said they didn't have a strategy when ISIS was on the march. Now it's clear their only strategy is airstrikes and training Iraqi forces behind the base that aren't yet capable."

"It doesn't look like a winning strategy."
