The treaty, revised from the original 1951 agreement, states that the United States will help defend Japan if it is attacked, and also provides for the continued use of bases and ports by the U.S. military. It was signed on January 19 but went into effect only after Prime Minister Nobusuke Kishi forced it through the Japanese legislature. Because of widespread protests (photo) -- many Japanese resented the American presence, opposed an alliance with a nuclear-armed U.S. and feared Japan might be pulled into a war not of its own making -- President Eisenhower had canceled a planned trip; Kishi would resign following ratification.
