Hey, bubbles, it is the Cuban - Hispanic war. After the yanks entered, then it became the Cuban - Hispanic - American war .
The reason to enter was that the USA were in the imperialistic phase, trying to extend their influence beyond the country. They had been waiting for the appropriate moment to intervene and try to seize Cuba. They also seized Puerto Rico, the Philippines and some other territories.

The Cubans had been fighting for their independence since 1868 and did not tolerate the USA rule, then the USA had no other choice than to grant their independence, but with the Platt amendment, that allowed them to intervene in Cuba whenever they wanted to
