A small price to play for their liberty...
The Platt Amendment’s conditions prohibited the Cuban Government from entering into any international treaty that would compromise Cuban independence or allow foreign powers to use the island for military purposes. The United States also reserved the right to intervene in Cuban affairs in order to defend Cuban independence and to maintain “a government adequate for the protection of life, property, and individual liberty.” Other conditions of the Amendment demanded that the Cuban Government implement plans to improve sanitary conditions on the island, relinquish claims on the Isle of Pines (now known as the Isla de la Juventud), and agree to sell or lease territory for coaling and naval stations to the United States. (This clause ultimately led to the perpetual lease by the United States of Guantánamo Bay.) Finally, the amendment required the Cuban Government to conclude a treaty with the United States that would make the Platt amendment legally binding, and the United States pressured the Cubans to incorporate the terms of the Platt Amendment in the Cuban constitution.
A fair deal for all concerned. And a good deal for Cuba.
