Federal agencies agree that terrorist activity in North Africa presents a growing security threat to U.S. interests. Vast ungoverned spaces, porous borders and groups aligned with al Qaeda have raised concerns about the area becoming a safe haven for terrorists to launch attacks against the United States. But the agencies most responsible for implementing a key counterterrorism partnership program — the State and Defense departments and the U.S. Agency for International Development — can’t seem to agree on how to implement policy there.Disagreements between State and Defense over the control of personnel and activities, and funding fluctuations in USAID programs have hindered U.S. objectives in the region, according to a new report by the Government Accountability Office. In addition, agencies have no way of measuring the effectiveness of their activities.
