How many Americans are fighting with the Islamic State in Iraq and Syria? “It’s in the hundreds,” says Representative Mike Rogers (R., Mich.), chairman of the House Permanent Select Committee on Intelligence.
There are “hundreds” of Americans “that have at least one time traveled, participated, and trained with them. Some of them have drifted back [to the U.S.], some of them have gone to Europe,” Rogers says.
About the threat the Islamic State poses to Western nations directly, Rogers noted that the group appears to have carried out attacks on Europe already: “You saw the Brussels event, the attack on the Jewish Museum. That was, we believe, an ISIL-led or inspired event. So that was the first time that they had attacked, we believe, outside their borders.”
