How has President Obama waged the war on terror? As lawyer-in-chief, he promised to close the Guantanamo Bay detention camp and engaged his inner circle in wrenching debates over the price of liberty and security. As commander-in-chief, he has become a decisive and lethal warrior, dealing out drone strikes and death sentences to suspected terrorists around the world. Daniel Klaidman reveals Obama's struggle to balance high-minded idealism and hard-headed politics as it plays out behind closed doors from the Oval Office and the Justice Department to the Situation Room and the CIA. Based on hundreds of interviews with men and women throughout the White House and the national security establishment, Kill or Capture is a startling new portrait of our forty-fourth president.
