By 1926 U.S. companies owned 60% of the Cuban sugar industry and imported 95% of the total Cuban crop, and Washington was generally supportive of successive Cuban governments. However, internal confrontations between the government of Gerardo Machado and political opposition led to his military overthrow by Cuban rebels in 1933. U.S. Ambassador Sumner Welles requested U.S. military intervention. President Franklin D. Roosevelt, despite his promotion of the Good Neighbor policy toward Latin America, ordered 29 warships to Cuba and Key West, alerting United States Marines, and bombers for use if necessary. Machado's replacement, Ramón Grau assumed the Presidency and immediately nullified the Platt amendment. In protest, the United States denied recognition to Grau's government, Ambassador Welles describing the new regime as "communistic" and "irresponsible".
