Nearly eight months ago, some of President Obama’s senior intelligence officials were already warning that ISIS was on the move. In the beginning of 2014, ISIS fighters had defeated Iraqi forces in Fallujah, leading much of the U.S. intelligence community to assess they would try to take more of Iraq.

But in an interview that aired Sunday evening, the president told 60 Minutes that the rise of the group now proclaiming itself a caliphate in territory between Syria and Iraq caught the U.S. intelligence community off guard. Obama specifically blamed James Clapper, the current director of national intelligence: “Our head of the intelligence community, Jim Clapper, has acknowledged that, I think, they underestimated what had been taking place in Syria,” he said.

Reached by The Daily Beast after Obama’s interview aired, one former senior Pentagon official who worked closely on the threat posed by Sunni jihadists in Syria and Iraq was flabbergasted. “Either the president doesn’t read the intelligence he’s getting or he’s bullshitting,” the former official said.

Clapper did tell The Washington Post ’s David Ignatius this month that he underestimated the will of the ISIS fighters in Iraq and overestimated the ability of Iraq’s security forces in northern Iraq to counter ISIS. (He also said his analysts warned about the “prowess and capability” of the group.)

Still, other senior intelligence officials have been warning about ISIS for months. In prepared testimony before the annual House and Senate intelligence committees’ threat hearings in January and February, Lt. Gen. Michael Flynn, the recently departed director of the Defense Intelligence Agency, said the group would likely make a grab for land before the end of the year. ISIS “probably will attempt to take territory in Iraq and Syria to exhibit its strength in 2014.” Of course, the prediction wasn’t exactly hard to make. By then, Flynn noted, ISIS had taken the cities of Ramadi and Fallujah, and the demonstrated an “ability to concurrently maintain multiple safe havens in Syria.”

The ability of ISIS to hold that territory will depend on its “resources, local support, as well as the responses of [Iraqi security forces] and other opposition groups in Syria,” Flynn added. He noted that while many Sunnis likely opposed ISIS, “some Sunni tribes and insurgent groups appear willing to work tactically with [ISIS] as they share common anti-government goals.”

Flynn was not alone. Clapper himself in that hearing warned that the three most effective jihadist groups in Syria?one of which he said was ISIS?presented a threat as a magnet for attracting foreign fighters. John Brennan, Obama’s CIA director, said he thought both ISIS and Jabhat al-Nusra, al Qaeda’s formal franchise in Syria, presented a threat to launch external operations against the West.

Sen. Dianne Feinstein, the chairwoman of the Senate Select Committee on Intelligence, said February 4 that because of areas of Syria that are “beyond the regime’s control or that of the moderate opposition,” a “major concern” was “the establishment of a safe haven, and the real prospect that Syria could become a launching point or way station for terrorists seeking to attack the United States or other nations.”
