Is Ukraine currently a democracy?
If part of your population is under occupation, they won't be able to vote how they want, and the rest of your civilian population becomes a target for constant bombardment in order to vote "correctly".
Summary: While questions have been raised about Ukraine’s democratic process, the country is acting in accordance with its constitution. Parliament overwhelmingly affirmed Zelenskyy’s legitimacy, and under Ukrainian law, elections cannot be held while martial law is in place. Despite the challenges of war, Zelenskyy maintains a 57% approval rating, and his mandate is not disputed by the Ukrainian people or their elected representatives.
