Fox News host Greg Gutfeld clashed with liberal guest Alan Colmes Thursday night, pushing back against Colmes’ contention that the Islamic State does not currently pose a direct threat to the United States.

“Why is it that lefties like you … have a hard time identifying actual existential evil unless it’s a Republican or a stay-at-home mom, where you can condemn them?,” asked Gutfeld, who was filling in for Bill O’Reilly. ”But when it comes to somebody who wants to kill you, oh, you know, they’re nobodies.”

Colmes, who posited that it seems as though the Islamic State threat is being ginned up in an effort to potentially lead the U.S. into another war, said that he was by no means defending the Islamic State, but that he didn’t want to see yet another American-led conflict unfold.

“I guess what it is is they’re not reaching the Colmes level of barbarism,” Gutfeld said. “They’re just not vicious enough for you.”

But Colmes held his ground, noting that the Islamic State would “have to be a threat to the homeland of the United States of America,” in his view, in order for U.S. involvement to be warranted.

Gutfeld, though, disagreed, calling the liberal commentator’s views on the matter “false.”

“Why is it our battle to be in a fight between Shiites and Sunnis, which has cost us treasure, which has cost us American lives for a decade or more?,” Colmes asked.
