@cicerone imposter,
A hundred years ago Guantanamo was strategically important as a US naval base, but nowadays it serves no useful purpose because of America's global reach via carrier groups and stealth bombers etc.
But if there's one thing history has shown is that once you control territory, you should NEVER voluntarily give it up.
For example France and Russia sold Louisiana and Alaska to America and have regretted it ever since.
Guantanamo is only small potatoes by comparison, but US politicians can't give it up even though they might want to, because they see the world as a series of squares on a chessboard which should be hung onto forever..
