A new report from the West Point counterterrorism center describes ISIS as a threat that had been growing for four years.

The report shows a long trail of warning signs, and it says that ISIS “had been steadily strengthening and actively shaping the future operating environment for four years.”

A senior State Department official answered "probably" when asked by Fox News whether the ISIS threat will last beyond President Obama's term in office.

On The Kelly File last night, House Intelligence Committee Chairman Mike Rogers (R-MI) warned that "this is as dangerous a threat matrix as I have ever seen."

On Outnumbered this afternoon, the hosts discussed whether President Obama ignored ISIS while it steadily grew into a terrorist army capable of holding territory in Iraq and Syria.

“The greatest trick the devil ever played on us, on the world, is getting us to believe he did not exist,” said Stacey Dash. “Obama thinks if he closes his eyes like a kid, it’s not there. He ignored the problem, and now it’s a crisis. I believe we have to strike. They killed an American. But I don’t know if he’s going to do that.”

She went on to note that any attacks by ISIS in the future are "on his hands."

Sandra Smith cited Rogers' warnings about 500 Canadians having joined ISIS, posing an immediate threat to the northern border of the U.S.

Kirsten Powers said it's "common sense" to figure out that ISIS had been steadily building up for years.

"These kinds of things don't happen overnight. ... You don't need a report from West Point to tell you that this is something that the administration should have known," said Powers.
