Combating WMD Terrorism

"One of the most difficult challenges we face is to prevent, deter, and defend against the acquisition and use of WMD by terrorist groups. The current and potential future linkages between terrorist groups and state sponsors of terrorism are particularly dangerous and require priority attention. The full range of counterproliferation, nonproliferation, and consequence management measures must be brought to bear against the WMD terrorist threat, just as they are against states of greatest proliferation concern."
