Today, July 25, 1972, is Constitution Day. It is the twentieth anniversary of the founding of the Commonwealth of Puerto Rico, or, more accurately, of “The Free Associated State” that links a speck in the Caribbean, 110 by 35 miles of subtropical hills and beaches, to the United States of America. It is also the seventy-fourth anniversary of the day when American troops landed in Guanica, Puerto Rico—just about where Columbus landed on his second voyage in 1493—to take possession of the former Spanish colony, ceded at the Treaty of Paris, America's victory prize in the Spanish-American War.
