The U.S. UAV operations and use of missiles to kill Islamic terrorists has been deadly, mainly for known Islamic terrorists and any unknown followers unlucky enough to be in the vicinity when the missile arrives. This has had a striking impact on the number of Western recruits for Islamic terrorism. A few years ago there were several hundred of these in Pakistan. But then their home countries publicized that they knew who many of these men were. That caused some 90 percent of these Western terrorists to leave. Many Islamic terrorist leaders have fled also, but for those who remain in Pakistan the threat of American missiles is less frightening than going home or to another questionable terrorist sanctuary. Most of these places, like Somalia, Yemen, and northern Mali, have lately become more dangerous for Islamic radicals. At least in North Waziristan you don’t have to worry about the local security forces and American missiles.
