political status of Puerto Rico

The current political status of Puerto Rico is the result of various political activities within both the United States and Puerto Rican governments. Politically, Puerto Rico is an unincorporated territory of the United States, which according to the U.S. Supreme Court's Insular Cases is "a territory appurtenant and belonging to the United States, but not a part of the United States within the revenue clauses of the Constitution." The basic question regarding this issue is whether Puerto Rico should remain a U.S. territory, become a U.S. state or become an independent country.
