The US, the EU and NATO intervened in Ukraine, which resulted in civil war. Russia had nothing to do with it.
“Since the interference and subversion of the USA, the EU and NATO, a precarious civil war takes place in the country which, at the same time, is the driving force of an impending war against Russia… The ‘Ukrainian democracy movement’, the “Maidan”, was a chimera, an invention cooked up in the poisonous kitchens of the Western secret services”.
No evidence given. Recurring pro-Kremlin disinformation about the war in Ukraine and Ukraine's statehood.
The Office of the Prosecutor of the International Criminal Court has stated that "the information available suggests that the situation within the territory of Crimea and Sevastopol amounts to an international armed conflict between Ukraine and the Russian Federation". This international armed conflict began at the latest on 26 February when the Russian Federation deployed members of its armed forces to gain control over parts of the Ukrainian territory without the consent of the Ukrainian government.
