The key point though is that it’s up to the people of Ukraine to decide if they want referendums. It’s not for an imperialist power like Russia to impose their own demands that Ukraine should hold referendums.
If Ukrainians wanted another leader like Yanukovych then they could have elected one in 2014 or 2019, but they didn’t.
Maybe Ukraine should have another election but it would be difficult when much of their land is illegally occupied by Russia.
Liberated regions like Kherson, liberated from the Russian invaders? Maybe they have had local elections, I dunno.
The parts of Ukraine that have been invaded by Russia have not been liberated, they have been subjugated to the rule of the Kremlin. And as I said before, “elections” in Russia are rigged. It’s not just ballot stuffing, it’s also the fact that genuine opposition candidates aren’t allowed to stand for election.
And as far as I understand, Zelenskyy and Poroshenko were both pretty pro-EU all along.
I don’t know why you’re going on about a “nazi problem” when Russia has plenty of far-right activists themselves.
