Pick any map of the world and point to a country. Chances are, the United States has some kind of formal relationship with it. But "ally" isn't just a diplomatic nicety — it's a loaded word that means different things depending on who's saying it and why.
Real talk? The list of U.S. allies shifts with the wind of geopolitics, economic interests, and sometimes sheer convenience.
