Sure, why not? The USA should also give back all the land it took from Mexico, meaning: California, Arizona, New Mexico. Maybe Texas, but that's debatable, because the Texans were independent for awhile. And then give back Guantanamo to Cuba. And give Puerto Rico to the Puerto Ricans. And so on.... :) It's a looooong list! I'm not going to hold my breath waiting for it to happen.
