How?If Ukraine really wants to be anything other than a tool of NATO they should start with fair elections.
Many of their people are in occupied territory. Many of their people have been kidnapped and wouldn't be allowed to vote. And it wouldn't exactly be fair due to the genocide that Russia has been engaging in.
Note the 2014 "election" about the "breakaway" provinces was both utterly rigged (status quo ante wasn't on the ballot) and utterly unfair (the Russian army troops were allowed to vote.) Thus we have already effectively had an election: by rigging it Russia proved that they knew the outcome would not go how they wanted, thus we know the people actually wanted to stay with Ukraine.
