However, U.S. was satisfied with Cuba being in the hands of the weak Spain, instead of going to some stronger nations like Britain or France. U.S. was even ready to use military forces in order to seize Cuba, in the name of national security (Tulchin & J.S., 1988).
After the end of the US Civil War (1861-1865), in order to maintain the business environment with the Latin America, a meeting was called in 1889, with the aim of assembling the Latin American nations under the leadership of the United States and opens the markets of Latin America to U.S. traders. Later, U.S. interfered in a conflict between Cuba and Spain, in order to acquire Cuba, which lead to the Spanish-American War in 1898. Later in 1902, the U.S. army left Cuba after the Platt Amendment was passed in 1901. According to this, U.S. was allowed to interfere in the happening in Cuba , in order to preserve the independence of Cuba and Cuba would not transfer its land to any other country other than the United States. In 1904, President Roosevelt justified the U.S.’s intervention in other state’ affairs as the responsibility of US to act as “international police power” and keep a check on anything wrong happening.
