The last permanent addition to American territory by force of arms was in the Spanish-American War, more than a century ago. Empires don't go home.

Unless I'm mistaken, all we held from then is Puerto Rico, which can vote itself independent or for full statehood at any time it chooses. It regularly chooses to do neither.

Also hold the U.S. Virgin Islands from the Spanish-American War. The author is wrong about that war being the last that we acquired territory in. After World War II we have continued to hold Guam and the Marianas Islands, as well as several South Pacific Islands as American Territories.

Puerto Rico, Guam, and a bunch of islands somewhere way out in the Pacific. We also took Cuba, which we granted independence, and the Philippines, which we held onto until 1947 or thereabouts.
