There is fascism in Ukraine. However it is not Ukrainian, but American fascism in foreign policy, which is carried out by the government of Ukraine which, in turn, is controlled by the United States (through, for instance, NABU [National Anti-Corruption Bureau of Ukraine]).
Biden has virtually promised a war on Russia.
This is another pro-Kremlin disinformation narrative about the aggression of the USA which supposedly threatens Russia.
Joe Biden, the now President-Elect of the USA has not promised a war on Russia. Biden has declared that Russia should be held accountable for interference in elections if it is proven. In the same piece, you can read his other criticisms of Russia, and belief that Russia wants to break up NATO and the EU. Nowhere has the President-Elect talked about, or threatened, any sort of war with Russia.
