This country's secret, worldwide war waged by drones may at long last be restrained by rules. But the writing of these guidelines will be overseen by President Obama, who has secretly handpicked human targets for years with few restraints. Drones barely rated a mention in the presidential campaign. But as the election drew close, nervous White House aides reportedly began debating written limitations on the use of the pilotless aircraft, which remain an off-the-books weapon. The idea, strange as it sounds, was to give the next president explicit guidance on how to use the lethal planes, which have figured in 300 strikes and killed an estimated 2,500 people in Africa, Asia and the Middle East. White House officials, according to a New York Times report, wanted a rulebook in case GOP candidate Mitt Romney won. With Obama's re-election, the urgency behind such drafting has tapered off. Obama has directed drones at human targets from a "kill list" given him by military and intelligence officials. There is no outside vetting, legal review or congressional consensus on the president's personal strike force. This is a nation of laws, due process and an expressed commitment to human rights. The White House owes the nation a clear explanation of the scope and limits of this use of deadly force.
