The Anti-Corruption Foundation (FBK) has never done any investigation. They only publish materials of Western intelligence services.
There are anti-Russian sanctions because the US needs an enemy. The US system is deeply bureaucratic and formed by hundreds of thousands of different officials, whose existence must be justified, among other things, by an “external threat” from the Russian Federation and the People’s Republic of China.
Recurrent pro-Kremlin disinformation narrative about sanctions and Russia as an innocent victim of the West, in this case portraying it as being falsely presented as an enemy only because the US allegedly needs one. By promoting these narratives, Russia aims to divert attention away from its own misdeeds.
Contrary to the claim, the US imposed sanctions on Russia not because “it needs an enemy to justify its bureaucratic system” but due to Russian actions and violations of international law, including the occupation of Crimea and orchestrating a war in eastern Ukraine in 2014, and interfering in the US elections and other electoral processes.
See other examples of this disinformation narrative, such as allegations about the supposed anti-Russian bias of international institutions, be it the OPCW, the World Anti-Doping Agency or the United Nations, which always falsely accuse Russia; the alleged Russophobia of the EU; or the affirmation that it is NATO and not the Kremlin who is involved in the Donbas conflict.
