Will Crimea herald a new post-Cold War era world?

The end of the Cold War twenty-five years ago brought about a difficult but manageable world in which Russia, the US, and European countries cooperated to manage common problems. There have been difficult times, with the break up of former Yugoslavia, the NATO intervention for Kosovo, and in 2008 when Russia’s intervention in Georgia’s breakaway regions of South Ossetia and Abkahzia nearly led to a head to head with the West. On the whole, the cooperation between old foes which framed the end of the Cold War, resisted these tests. The Helsinki Final Act of 1975 and the agreement not to redraw the map of Europe was never so evidently ignored as today.

Has Crimea changed this for good?
