From the Wall Street Journal editorial page:

Putin’s Prisoner Khodorkovsky dared entertain political ambition. Five years to the day after his arrest and incarceration in a Siberian prison camp, former Yukos CEO Mikhail Khodorkovsky might have a rueful reason to smile. The ruble is at a two-year low, the Russian stock market is down 70% from its highs, and the price of energy is plunging. The bill for the Kremlin’s economic cronyism and disdain for the rule of law is coming due.
