Rightly, they claim why Zelenskyy stands for sanctions. Of course, he will advocate sanctions. After all, sanctions are an initiative of the American Congress and the Senate. How can the President of Ukraine say no, when the American Congress, the European community speak of sanctions?

Conspiracy theory with no evidence given. The message advances a recurring pro-Kremlin disinformation narrative denying Russian responsibility for armed aggression in Ukraine. The international community, including the European Union recognizes and condemns clear violations of Ukrainian sovereignty and territorial integrity by acts of aggression by the Russian armed forces since February 2014. The allegation that a Ukrainian energy company would "push for the war" in east Ukraine does not quite square with another recurring pro-Kremlin narrative, which paints the conflict as an "uprising" of local militias against the illegitimate post-Euromaidan government in Kyiv.
