In April 1898 Senator Henry M. Teller (Colorado) proposed an amendment to the U.S. declaration of war against Spain which proclaimed that the United States would not establish permanent control over Cuba. It stated that the United States "hereby disclaims any disposition of intention to exercise sovereignty, jurisdiction, or control over said island except for pacification thereof and asserts its determination, when that is accomplished, to leave the government and control of the island to its people."
Happy to help, have a great day!
