As vice president, Richard B. Cheney famously spent much of the past eight years in undisclosed locations and offering private advice to President George W. Bush. But past was not prologue.
Today Cheney is the most visible -- and controversial -- critic of President Obama's national security policies and, to the alarm of many people in the Republican Party, the most forceful and uncompromising defender of the Bush administration's record. His running argument with the new administration has spawned a noisy side debate all its own: By leading the criticism, is Cheney doing more harm than good to the causes he has taken up and to the political well-being of his party?
