Ukraine’s interim prime minister, Arseniy Yatsenyuk needs to speak with eastern European countries such as Poland about the willingness and integrity of Obama and his administration. Ukraine needs to use EU allies such as Merkel to broker a draw down of escalation and the actual removal of troops from Crimea. Putin is a chess player and I am certain that his posturing with Crimea is to get the Ukrainian government to keep the ties with Russia and be part of the bloc as the previous Russian crony had decided. Yatsenyuk needs to be cautious with his words and urgent admonition that Ukraine is looking westward and that is where it will go. He needs to focus on the matter about his country and Russia and put that matter to the side. It may be quite possible once he talks with Putin to identify a third option that will allow both sides to get what they want.
But still — bottom-line —- For the sake of the Ukrainians, Yatsenyuk do not rely on Obama.
