The primary actions of Zelenskyy should be arranging a real ceasefire in Donbas and acknowledging that Russia does not wage a war against Ukraine, rather a civil war is going on between the Russian-speaking and Ukrainian-speaking population.
This message contains a classic pro-Kremlin narrative about the war in Ukraine. It denies Russia's implication in the Donbas conflict and puts forward a false claim that a civil war between the Russian-speaking and Ukrainian-speaking population is going on. It disregards the extensive irrefutable factual evidence confirming an ongoing Russian military presence in Donbas that can be found here and here.
At the NATO Summit in Wales in September 2014, NATO leaders condemned Russia’s military intervention in Ukraine in the strongest terms and demanded that Russia stop and withdraw its forces from Ukraine and along the country’s border. NATO leaders also demanded that Russia complies with international law and its international obligations and responsibilities; end its illegitimate occupation of Crimea; refrain from aggressive actions against Ukraine; halt the flow of weapons, equipment, people and money across the border to the separatists; and stop fomenting tension along and across the Ukrainian border. The European Union stated in July of 2014 that "arms and fighters continue flowing into Ukraine from the Russian Federation".
