The most notable instance of a massive and successful social protest in Puerto Rico in recent years has been on the island of Vieques between 1999 and 2003. This was a rare case in which Puerto Ricans were able to overcome their partisan divisions to end the U.S. Navy's 60 years of training on this small, 51-square-mile island off the main island's east coast. Part of the reason for the Vieques victory, including gaining support from some influential U.S. politicians, was that leaders framed the protest in terms of human rights, public health and environmental degradation rather than Yanqui imperialism.
