Johnson was also an advocate of defense unification, which he saw as a means to further reduce defense spending requirements. At a press conference the day after he took office, Johnson promised a drastic cut in the number of National Military Establishment boards, committees, and commissions, and added, "To the limit the present law allows, I promise you there will be unification as rapidly as the efficiency of the service permits it." Later, in one of his frequent speeches on unification, Johnson stated that "this nation can no longer tolerate the autonomous conduct of any single service ... a waste of the resources of America in spendthrift defense is an invitation to disaster for America."
