The Ukrainian constitution does not allow for elections to be held during periods of martial law, which was declared at the start of the war.
If there is ever a good time to declare martial law, being invaded by a neighboring country might qualify as a justifiable time.
In any case, it's constitutional, but Ukrainian political process isn't what we are here to talk about.
Fundamentally, I agree with you - If the majority of Ukrainians were to decide they don't want the war to continue, the war should stop. The number show, however, that the people are not ready to give up.
You don't get to set the topic. If you don't want to discuss it then nobody can compell you to do so. Don't pretend it's irrelevant to the topic you've chosen to engage with just because it's inconvenient for your arugment to engage with it.
The topic is technically "did China supply Russia with weapons etc?" But the topic we've been talking about for a bit now is "is the invasion justified," not "is the Ukrainian constitution constructed in an ideal way."
The ideal-ness of the constitution has no bearing on whether the invasion was justified, because invading your neighbor and killing thousands of civilians, even if their constitution is not completely ideal, cannot be justified.
I'm officially announcing now that I am going to sleep. Goodnight, and I hope you can all do some reflecting on whether invading neighboring countries is good or bad. I'm done responding to all of this.
