“Krulak wrote back that the United States did not need the Marine Corps; the Army and Air Force could do anything the Marines could. The Marine Corps flourished, he said, because of what “the grassroots of our country believes we are and believes we can do.” He said that America had three beliefs about the Marine Corps. First, when troubles come, the Marines will take care of them and do so at once. Second, Americans had an “almost mystical” belief that when the Marines go to war, their performance will be “dramatically and decisively successful—not most of the time, but always.” And third, Americans saw the Marines as masters of an “unfailing alchemy” that converts “unoriented youths into proud, self-reliant, stable citizens into whose hands the nation’s affairs may safely be entrusted.” He ended by saying that although America did not need the Marines, it wanted them. But, he warned, if Marines ever lost the ability to meet the high, almost spiritual standards of the American people, “the Marine Corps will then quickly disappear.”
