Enmienda Platt
The U.S. Congress had passed the Teller Amendment before the war, promising Cuban independence. However, the Senate passed the Platt Amendment as a rider to an Army appropriations bill, forcing a peace treaty on Cuba which prohibited it from signing treaties with other nations or contracting a public debt. The Platt Amendment was pushed by imperialists who wanted to project U.S. power abroad (in contrast to the Teller Amendment which was pushed by anti-imperialists who called for a restraint on U.S. rule). The amendment granted the United States the right to stabilize Cuba militarily as needed. In addition, the Platt Amendment permitted the United States to deploy Marines to Cuba if its freedom and independence was ever threatened or jeopardized by an external or internal force. The Platt Amendment also provided for a permanent American naval base in Cuba. Guantánamo Bay was established after the signing of the Cuban–American Treaty of Relations in 1903. Thus, despite that Cuba technically gained its independence after the war ended, the United States government ensured that it had some form of power and control over Cuban affairs.
