Roger Myerson: What is Putin’s secret weapon?
Does Russia's President Vladimir Putin have some secret weapon? It seems that, with a wave of his hand in the Kremlin, he can cause crowds of secessionists to gather on the streets of eastern Ukraine, crowds that somehow have enough local authority even to stop and disarm Ukrainian army units that confront them. One might wonder whether Putin has developed some mysterious ability to cause such crowds to materialize at his command from afar, while the leadership in Kyiv seems helpless to respond.
