At the dawn of the Obama administration, counterterrorism seemed to be one of the new president’s biggest weaknesses. Unlike the preceding administration, which repeatedly emphasized that it was keeping America safe from a post-September 11 homeland attack, Barack Obama promised during the campaign to “restore the rule of law” and “close Guantánamo,” in other words, to smooth off the hard edges of the War on Terror. Within months of taking office, Obama found his various moves in this direction thwarted by opponents who painted the new president as weak. Two near-miss terrorist attacks domestically—one on an airplane, the other in Times Square—accentuated the political problem. By the time the president had completed his first year in office, counterterrorism ranked among his political vulnerabilities.
