In December 2008, Chris Wallace asked Vice President Cheney, “If the president, during war, decides to do something to protect the country, is it legal?” Cheney’s answer included a reference to a military authority that President Bush did not exercise. “The President of the United States,” he said, “now for fifty years is followed at all times, twenty-four hours a day, by a military aide carrying a football that contains the nuclear codes that he would use and be authorized to use in the event of a nuclear attack on the United States.” The vice president added that the president “could launch the kind of devastating attack the world has never seen” without checking with Congress or the courts, and noted also that “he has that authority because of the nature of the world we live in.” And then he shifted to the war on terrorism: “It’s unfortunate, but I think we’re perfectly appropriate to take the steps we have.”

"A Moral Revolutionary" by Garry Wills (09/13/82) The life and trials of MLK.

In the tumultuous history of postwar American conservatism, defeats have often contained the seeds of future victory. In 1954, the movement's first national tribune, Senator Joseph McCarthy, was checkmated by the Eisenhower administration and then "condemned" by his Senate colleagues. But the episode, and the passions it aroused, led to the founding of National Review, the movement's first serious political journal. Ten years later, the right's next leader, Barry Goldwater, suffered one of the most lopsided losses in election history.
