An asian island was named (re-named) USA ( not U..S..A.) for marketing purposes
A new American country may be born and, you guess it...or an old American country may decide to modify or change its name and, you guessed it again...But do they actually have to be in America to do it? One of those Arab countries may just like the A merica. They invented the decimal numbering system so they may just as well adopt the whole alphabet for any disputable purpose..
