For the many people who have engaged in the struggle for Puerto Rico’s independence, July 25 has a special significance. On that date in 1898, U.S. troops invaded Puerto Rico, beginning a period of U.S. colonial domination on the island that continues to this day. The United States invaded Puerto Rico, along with the Philippines, Guam and Cuba, in the setting of the Spanish-American War. That war was the opening of what would be the menacing role and predatory nature of the U.S. capitalist class in the Caribbean, Latin America and the entire world.
