Between the first and second world wars, the US Marine Corps engaged in questionable activities in the Banana Wars in Latin America. Retired Major General Smedley Butler, who was at the time of his death the most decorated Marine, spoke strongly against what he considered to be trends toward fascism and militarism. Butler briefed Congress on what he described as a Business Plot for a military coup, for which he had been suggested as leader; the matter was partially corroborated, but the real threat has been disputed. The Latin American expeditions ended with Franklin D. Roosevelt's Good Neighbor policy of 1934.
