This is a recurring pro-Kremlin disinformation narrative combining the war in Ukraine, Euromaidan, and Nazi/Fascist Ukraine.
The war in Ukraine is not a civil conflict but a well-documented act of aggression by Russian armed forces, ongoing since February 2014.
There is irrefutable evidence of direct Russian military involvement in Ukraine. 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 2014 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."
Additionally, there was no coup d'état in Ukraine in February 2014. The spontaneous onset of the Euromaidan protests was an organic reaction by numerous parts of the Ukrainian population to former President Yanukovych’s sudden departure from the promised Association Agreement with the European Union in November 2013.

As far as agreements for a political solution are concerned, Kyiv has repeatedly stated that it seeks a peaceful solution in Donbas and that the Minsk agreements are the only option to end the war there. Ukraine is not at war with millions of people from Donetsk and Luhansk as pro-Kremlin disinformation outlets often like to portray it. These claims intentionally misrepresent the reality of Russia's direct and crucial important support to separatist militant groups in Eastern Ukraine.
The involvement of Russian personnel and equipment in the creation of the DPR and LPR has been well documented already for years. The destabilisation of Eastern Ukraine and the illegal annexation of Crimea has been condemned by the Council of the European Union and led to restrictive measures since 2014.
