At this year's final meeting of the Verkhovna Rada, the Ukrainian officials seem to have decided to ultimately put an end to Ukrainian-Russian relations.
The officials prepared an address to President Poroshenko, asking him to sever all diplomatic ties and transportation links with Russia, as well as declare an actual war on Moscow.
It's possible that their decision might have been influenced by the wild office party held the day before by the Poroshenko Bloc together with its founder.
