Wow. Quite a bombshell from the New York Times' C. J. Chivers - How Top Spies in Ukraine Changed the Nation's Path.
Also, yet another proof that what's happened in Ukraine is not going to happen in Russia anytime soon:
Throughout the crisis an inside battle was waged by a clique of Ukraine's top intelligence officers, who chose not to follow the plan by President Leonid D. Kuchma's administration to pass power to Prime Minister Viktor F. Yanukovich, the president's chosen successor. Instead, these senior officers, known as the siloviki, worked against it.
Such a position is a rare occurrence in former Soviet states, where the security agencies have often been the most conservative and ruthless instruments of state power.
