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....
The officers funneled information to Mr. Kuchma's rivals, provided security to opposition figures and demonstrations, sent choreographed public signals about their unwillingness to follow the administration's path and engaged in a psychological tug-of-war with state officials to soften responses against the protests.
Ultimately, the intelligence agencies worked - usually in secret, sometimes in public, at times illegally - to block the fraudulent ascension of Mr. Yanukovich, whom several of the generals loathe. Directly and indirectly, their work supported Viktor A. Yushchenko, the Western-oriented candidate who is now the president-elect.
