Would America happily just give up Guantanamo Bay Naval Base - no, and that goes back to 1898.
Jimmy Carter happily gave up the Panama Canal but of course we know that the pooty toot is no Jimmy Carter. Great argument, n’est pas?
Since Obama attended the Russian-American University at the behest of Zybiegnew (instead of Columbia), I suspect Obama has made a deal with Putin. Obama will not intervene in Russian affairs and Putin will come to Obama’s aid during a civil war. NO proof, but possible.
