Lets Get Real:
The Russians are pushing to see how far they can go before the US either reacts or gets a new US President. Latest deal between Assad's Syria and Russia shows how much influence the US has lost, the US with Obama in the Oval Office is no longer seen as a threat that has to be handled with care, thus if the Russians re-open their bases in Cuba and Vietnam it will show how much of a disaster the Obama Administration has been to World Security. The next US President, and lets assume its HRC, will have to stand tough when it comes to Putin, this could cause a crisis in itself, a new Administration could no show weakness or its power in World affairs would be over. Thus watch this space, it could get frosty fast.
