question: By May 1969, the level of intensity of the conflict had reduced substantially. Isolated incidents continued to occur particularly along the ROKA-controlled sectors of the DMZ, but it had become clear that the North had abandoned its hopes of starting an insurgency in the South. Qualitative improvements in the ROK Army meant that the U.S. could start to contemplate reducing its military presence in South Korea. On 25 July 1969, President Nixon announced his Nixon Doctrine that, henceforth, the U.S. expected its allies to defend themselves with U.S. air and seapower support , but not U.S. ground troops. While aimed primarily at South Vietnam, this policy would also apply to South Korea . On 1 October 1969 General Bonesteel handed over command of USFK to General John H. Michaelis. One of General Michaelis' early tasks was negotiating the release of three U.S. soldiers captured when their OH-23 helicopter was shot down after straying across the DMZ; their release on 3 December 1969 is regarded as the official end of the conflict.
Answer this question: How many months after President Nixon announced his Nixon Doctrine did the conflict officially end?
answer: 5

question: The United States occupation of Nicaragua from 1912 to 1933 was part of the Banana Wars, when the US military forcefully intervened in various Latin American countries from 1898 to 1934. The formal occupation began in 1912, even though there were various other assaults by the U.S. in Nicaragua throughout this period. American military interventions in Nicaragua were designed to stop any other nation except the United States of America from building a Nicaraguan Canal. Nicaragua assumed a quasi-protectorate status under the 1916 Bryan-Chamorro Treaty. But with the onset of the Great Depression and Augusto C. Sandino's Nicaraguan guerrilla troops fighting back against U.S. troops, it became too costly for the U.S. government and a withdrawal was ordered in 1933.
Answer this question: Nicaragua assumed a quasi-protectorate status how many years after the start of the US occupation?
answer: 4
