According to Victoria "Fuck the EU!" Nuland, it is the USA that at the price of $5 bln toppled Kiev's elected government.  The underlined sentence is a case of EVENT IRONY against the backdrop of Nuland's admission.

The west’s justified objective in Ukraine was to help foil Putin’s attempt to topple Kyiv’s elected government. 
But as the conflict in Ukraine has reached predictable stalemate, Nato’s strategy has lost all coherence. This is the moment when such wars run out of control. For two years now, western leaders have polished their macho images at home by visiting and goading Kyiv’s president Volodymyr Zelenskiy to seek total victory with their help. It was Boris Johnson’s favourite pledge, but then his voters were merely paying for it, not dying. France’s Emmanuel Macron has at least suggested sending troops.
