Ukraine is sovereign and should be given the chance to defend itself against soviet expansionism. I don't see how being diplomatic and brokering a power transition is any sort of democratic impropriety. The author clearly has an agenda.
Ukraine lost its sovereignty in February 2014 after the coup d'etat and displacement of its legitimate president. The current Ukrainian "government" was de facto appointed by Biden and contains foreign nationals. Not a single Porosheno's move is done without a prior "by your leave" from Biden or Nudelman.
But Ukraine was steadily losing its sovereignty over the 25 years after the collapse of USSR, as American NGOs took root in all spheres of Ukrainian society, as Soros-funded falsified history books altered the mentality and conciousness of the young generation, and as Ukrainian oligarch sold national interests.
Interestingly, Russia was on the same express route to abyss during the 90s, and the destruction was halted when Yeltsin left the office and Putin somewhat reigned in the stealing bastards (oligarchs). This never happened in Ukraine.
And Ukrainians should not think that USA has their best interests at heart. The current destruction of the country is the best indicator of that. For US tops, Ukraine is nothing but a tool, a lever to get at Russia, it's viewed as expendable lose change.
