During the recent Summit on Violent Extremism held in Washington, D.C., President Barack Obama said that the U.S. battle against "violent extremism" doesn't mean it's a war on the Islamic world and using the words Muslim or Islamic offer the very terrorist group we are fighting a certain amount of legitimacy. However, the head of a congressional committee that oversees the nation's Homeland Security responded by saying to reporters, "[Obama and his administration] won't even call the threat what it is. How can you talk about defeating an enemy you cannot name?"
