There is not much we can do short of going to war with Russia. It may be that the Ukraine and The Crimea will just be divided.
Obama has not got the guts or the wits to play with Putin. He has not got an SOS with the brains or gravitas to carry out a plan if he had one.
The only chess piece to play is for the US and the EU to do what they did in the Georgia episode and make Putin believe he will be shunned by the West if he proceeds. Thats what Sarkozy flew to Moscow to tell him when he was getting ready to take all of Georgia. He got Ossetia and now he will get Crimea but not all of Ukraine. He’s been planning this for 5-6 years.
And pooty tooty will wait until he can slice off another ppiece of the salami. Hillary can also be flexible.
Hello? Obama's a Communist; he's in this right up to his hugely lobate ears. Hell, he's third- or fourth-generation Red here. What makes you think he will "stand up" to anything Putin the journalist-slayer cares to try?
