Your "source" is calling Zelensky "the Imperial Puppet" and "comedian"[0], which makes me think it's probably even more biased towards Russia than western media are towards Ukraine.
My understanding is Ukraine was ready to negotiate with Russia by April 2022. Boris Johnson, the former UK prime minister, went to visit [0] around April 9 2022. Thenceforth Zelensky seems to have understood that Ukraine was to fight to the last Ukrainian.
What actually happened is Ukraine retook Bucha and then when Ukraine saw what Russians did k Bucha they decided negotiations were over.
I don’t blame them either why would you negotiate with the army that’s raping and torturing your civilians?.
There’s no point to negotiation with Russia anyway they don’t abide by international agreements unless it benefits them and even they may break them later.
Any peace outside of an absolute Russian defeat would be temporary and just allow Russia to invade again later.
> Thenceforth Zelensky seems to have understood that Ukraine was to fight
You've given no evidence or argument to back up this implied conspiratorial causality. The simplest explanation is that Johnson told Zelensky that if Ukraine wanted to fight, they would have the support of the UK and the greater West.
Also, how hard is it to imagine that a country that had been subjugated by Russia up until a single generation ago, knows the horrors of such and will do everything possible to avoid ending up there again? The further east you go into previously Soviet countries, the more support there is for Ukraine. If this really were a "both sides" issue, you'd expect the exact opposite.
