Johnson welcomed the passage of the 1949 amendments to the National Security Act of 1947, telling an American Legion convention that he was "happy to report ... that 80 percent of the problems that beset unification immediately disappeared when the President signed the bill increasing the authority and the responsibility of the Secretary of Defense." Believing that the amendments would help him achieve additional budget cuts, Johnson estimated that one year after their passage the Defense Department would be achieving savings at the rate of $1 billion per year (he later claimed that he had attained this goal). One of his slogans was that the taxpayer was going to get "a dollar's worth of defense for every dollar spent" by the Pentagon, an approach that Truman approved.
