In April 2009, Rose spoke at the Hebrew University of Jerusalem. Rose said that Islam expert Bernard Lewis had told him that the cartoon crisis marked "the first time Muslims tried to impose Islamic law on non-Muslim countries." He also said, "There's a problem with Muslims in Europe and it must be dealt with – but limiting freedom of expression is not the solution." He further commented: "There are those who viewed the cartoons that I published as a form of incitement, but I don't think a statement should be measured by the response it yields, especially if the response is irrational and stupid." He also stated that "There was a time after the crisis that I had to take extra precautions, but that is in the past. I never felt threatened – or that I have to be silent."
