Appearing on MSNBC's Morning Joe on Thursday, David Rothkopf, CEO and editor of The FP Group, which publishes Foreign Policy magazine, warned against European authorities being too aggressive in fighting Islamic terrorism following the brutal attack in Paris: "I think we have to be just as worried about the reaction to the attack from nationalists, from right-wingers, from people who have sought to drive this wedge...between the Islamic communities and the mainstream communities in Europe....it's very important that we recognize the value of restraint in response to these things."
