US involvement in Cuban independence included all of the following except?

US involvement in Cuban independence included military support during the Spanish-American War and the subsequent establishment of a military government in Cuba. However, it did not include direct territorial annexation of Cuba, as the US opted for a protectorate arrangement instead. The Platt Amendment, which allowed US intervention in Cuban affairs, was also part of this involvement. Ultimately, while the US played a significant role in Cuba's independence from Spain, it did not pursue outright annexation.
