Referendums in Donbas, Zaporizhzhia and Kherson regions are a response to Zelenskyy's call for Russians to get out of Ukraine. What has been happening in Ukraine since 2014 is impunity. [Ukraine] finally turned into a totalitarian state of the Nazi persuasion. The Russian Federation has a lot of evidence of the criminal actions of the Ukrainian military.
Ukraine exists within unnatural borders. Transcarpathia should be ceded to Hungary, Galicia to Poland, Bukovina to Romania, Donbas and Crimea to Russia. These are other countries' territories.
Recurring pro-Kremlin disinformation narratives claiming that Ukraine has other countries’ territories which should be ceded to their rightful owners. This is a cynical attempt to indirectly draw other countries into Russia's unjustified and unprovoked invasion of Ukraine.
Poland, Hungary, and Romania respect Ukraine's sovereignty and territorial integrity. They do not pretend on Ukrainian territories and do not claim them. No neighbouring state, except the Russian Federation, has tried to violate Ukraine's territorial integrity. Ukraine’s sovereignty and territorial integrity are respected by almost the whole world with Russia as the key exception. Ukraine's sovereignty and territorial integrity have been violated by continuous acts of aggression by Russian armed forces since 2014 and culminated in an aggressive attack on a neighbouring country on February 24, 2022.

See earlier disinformation cases alleging that Poles are stoking nationalist sentiment in Ukraine in order to annex Lviv, that Poland thinks that Western Ukraine, Western Belarus and South-Western Lithuania belong to them, that Poland wants to dismember Ukraine and re-establish a Polish empire, that Ukraine will disintegrate and fall prey to territorial claims of EU member states, that Ukraine is a Western colony belonging to Poland, Hungary, Romania, and Russia.
