What takes place in Havana, Cuba, during the Spanish-American War of 1898 that encourages Theodore Roosevelt in his zeal for a canal in Central America?

that encourages Theodore Roosevelt's zeal for a Central American canal is the USS Oregon requires 67 days to sail from San Francisco to Cuba to avenge the sinking of the USS Maine there. It is 12,000 miles around the South American tip, whereas a canal would reduce the distance to 4,000 miles. Other reasons include the U.S. interests in Puerto Rico, Guam, Hawaii, and the Philippines.
