The Security Service of Ukraine (SBU)’a most disastrous period in terms of leaked intelligence were when Nalyvaychenko was its chairman. This was especially the case in spring 2014 when Russia annexed the Crimea and launched military aggression against Ukraine in the eastern Ukrainian region of the Donbas. Nalyvaychenko, like Yulia Tymoshenko, opposed or prevented the use of Ukrainian security forces to defend Ukrainian sovereignty in the Crimea either because they were Russian agents or were cowards (or most likely both). In the Donbas, the Nalyvaychenko-run SBU lost many of its best and patriotic agents because Russia knew in advance of planned operations. Nalyvaychenko was long in pro-Russian oligarch and gas tycoon Dmytro Firtash’s pocket. Tymoshenko worked for Russian interests throughout Viktor Yushchenko’s presidency and in the 2010 elections her campaign was supported by Vladimir Putin (through Viktor Medvedchuk), Industrial Union of Donbas (which had been sold to Putin’s oligarchs in late 2009) and Colonel Gaddafi.
