The essay begins: "All too often during my 4½ years as secretary of defense, when I found myself sitting yet again at that witness table at yet another congressional hearing, I was tempted to stand up, slam the briefing book shut and quit on the spot. The exit lines were on the tip of my tongue: I may be the secretary of defense, but I am also an American citizen, and there is no son of a bitch in the world who can talk to me like that. I quit. Find somebody else. It was, I am confident, a fantasy widely shared throughout the executive branch."
"Much of my frustration came from the exceptional offense I took at the consistently adversarial, even inquisition-like treatment of executive-branch officials by too many members of Congress across the political spectrum—creating a kangaroo-court environment in hearings, especially when television cameras were present. But my frustration also came from the excruciating difficulty of serving as a wartime defense secretary in today's Washington. Throughout my tenure at the Pentagon, under both President George W. Bush and President Barack Obama, I was, in personal terms, treated better by the White House, Congress and the press for longer than almost anyone I could remember in a senior U.S. government job. So why did I feel I was constantly at war with everybody? Why was I so often so angry? Why did I so dislike being back in government and in Washington?"
