Putin v. Khodorkovsky:

Almost a decade ago, Mikhail Khodorkovsky, then the owner of the Yukos Oil Company and Russia’s richest man, completely miscalculated the consequences of standing up to Vladimir Putin, then Russia’s president. Putin had Khodorkovsky arrested, completely miscalculating the consequences of putting him in prison. During his eight years in confinement, Khodorkovsky has become Russia’s most trusted public figure and Putin’s biggest political liability. As long as Putin rules Russia and Khodorkovsky continues to act like Khodorkovsky, Khodorkovsky will remain in prison—and Putin will remain terrified of him.
