"This is about Putin reacting to the loss of a sphere of influence, a loss of a proxy in Ukraine, the real blow to his plan to have some sort of counter organization to the European Union," Donilon said. "... The loss of Ukraine in his view...is really a traumatic event."
Russia insists its military moves in the Ukrainian peninsula of Crimea are to protect Russian installations and its citizens living there. Going forward, according to Donlion, the U.S. and the world have a few options, including economic sanctions, to deal with the situation in Ukraine.
As for Secretary of State John Kerry, specifically, Donilon said Kerry's goal during his visit to the region Tuesday is three-fold: "Number one is to indicate political support for the government in Ukraine, which is planning to have an election in May, that's absolutely critical. Number two is to bring the Ukraine pledges of and a plan for international community economic support. And third, to indicate that, in fact, the international community will continue to push back on Russian assertions that this is somehow a humanitarian mission. It is not. This is about in Ukraine right now an attempt to regain leverage in the situation."
