Eric Posner: Let Crimea go

Russian troops surround a Ukrainian military base in the village of Perevalnoye, outside the Crimean capital Simferopol, on March 3.
Crimea’s planned March 16 referendum on whether it should leave Ukraine and join Russia is underhanded, dishonest, and absurd—and completely legitimate. Vladimir Putin has yet again maneuvered the West into a corner. Jujitsu-like, he is using one of our most prized institutions—international law—against us. This is not the first time, and so calls to punish Russia and start a Cold War II are understandable. Yet we should swallow our pride and let him bask in his victory. In the long run, it gets him nothing.
