U.S. control, including the Philippines and Puerto Rico? Bryan and other anti-imperialists argued in the affirmative, while leading imperialists argued inthe negative. The issue was resolved in favor of the imperialists in a series ofSupreme Court cases (1901-1903) known as the insular (island) cases. TheCourt ruled that constitutional rights were not automatically extended to ter-ritorial possessions and that the power to decide whether or not to grant suchrights belonged to Congress.Cuba and the Platt Amendment (1901)Previously, the Teller Amend-ment to the war resolution of 1898 had guaranteed U.S. respect for Cuba'ssovereignty as an independent nation. Nevertheless, U.S. troops remained inCuba from 1898 until 1901. In the latter year, Congress made withdrawal oftroops conditional upon Cuba's acceptance of terms included in an amend-ment to an army appropriations bill-the Platt Amendment of 1901. Bitterlyresented by Cuban nationalists, the Platt Amendment required Cuba to agree( 1) to never sign a treaty with a foreign power that impaired its independence,(2) to permit the United States to intervene in Cuba's affairs to preserve itsindependence and maintain law and order, and (3) to allow the U.S. to maintainnaval bases in Cuba, including one permanent base at Guantanamo Bay.A Cuban convention reluctantly accepted these terms, adding them to itscountry's new constitution. In effect, the Platt Amendment made Cuba a U.S.protectorate. As a result, Cuba's foreign policy would, for many years, be sub-ject to U.S. oversight and control.
