Could that happen? Would Obama finally end the mess in Cuba by invading it and leave as soon as Putin leaves Ukraine?
Or would Obama close the Dardanelles and stop all Russian ships? He could claim it’s to protect Europe from a Crimea style takeover and only allow passage of ships that the NSA approved? That would get Putin’s attention.
How about buzzing the Russian Military that are in Eastern Ukraine? Maybe some dumb Putin guy will do something dumb and the jets could fire on him?
