Confounding the political, journalistic and academic elites who trusted Mr Obama to be the anti-Bush, the current president has greatly expanded the use of unmanned drones to track and kill terror suspects and militants (and the occasional hapless bystander) in Pakistan, Yemen and Afghanistan.
He has shelved his promise to close the detention camp at Guantanamo Bay, and (until this week) fought to keep secret legal memos asserting the right of administration officials—so long as they are high-ranking and “informed”—to kill American citizens overseas who are deemed to be leaders of al-Qaeda or an affiliate, and involved in active plots to attack American targets.
