His tenure as Chief Justice saw the issuing of several critical rulings that shaped American law and society, including four landmark decisions: Brown v. Board of Education (1954), Gideon v. Wainwright (1963), Reynolds v. Sims (1964), and Miranda v. Arizona (1966).
After most of the Republican contenders for the presidency were killed by the Soviet atomic bombing of Washington, DC in May 1952, only he and Dwight Eisenhower, who were not in Washington survived. However, it seemed that with Eisenhower's popularity, he would likely end up becoming the Republican nominee by default.
Warren was elected President in 1960 and was re-elected over Hubert Humphreyin 1964. When the Race's Colonization Fleet arrived at Earth in 1962, Warren ordered a secret attack using nuclear missiles fired from a satellite that destroyed a dozen of the Fleet's starships and killed thousands of civilians. Warren managed to conceal the USA's role in the attack until 1965, when the plot was uncovered and leaked to the Race by Sam Yeager through Straha--this despite Warren's best efforts to silence Yeager through draconian extralegal measures. FleetlordAtvar threatened war with the United States; having seen how quickly and easily the Race had defeatedGermany in the prior months, Warren knew he must avoid a war at all costs. Atvar offered two other options: abandon all space exploration for the indefinite future, or allow the Race to destroy an American city. Warren knew he must choose one of the two lest his country be destroyed; and he would not give up the space program, a sign of his country's might and technological prowess, and so he surprised and disappointed Atvar by allowing him to destroy Indianapolis. Warren then committed suicide in the Gray House, and was succeeded by his Vice President, Harold Stassen.
