The independence of Cuba.

Explanation:

The Spanish-American War's main problem originated in the Cuban fight for independence from Spain in 1895. During that time, the US invested on the island and it was better for its interests that Cuba achieved independence. The US Congress supported the independence movement and sent the USS Maine to Havana to ensure the safety of the Americans that lived there and the Americans interests, the problem was that the Main sank from a massive explosion that later was blamed on the Spanish which pushed to the beginning of the war.
