The West has very few options left to curb further Russian aggression in the Ukraine. After seizing Crimea many naively hoped that Russia would be content with having secured its access to the Black Sea and the future for its Black Sea Fleet base, and would not continue further efforts to destabilize Ukraine and seize more territory. These hopes have now been dashed, as Russia continues to sponsor and facilitate internal unrest throughout eastern Ukraine and amass armed forces along the Ukrainian border.
