“go directly to a peace agreement, which would end the war and not a mere ceasefire agreement, which often times do not hold up”

And who's to say that asshole Putin won't start up the war again? If he doesn't honor ceasefires, how can you trust him with peace by giving him what he wants? That's rewarding a dog for bad behavior.

So absolutely nothing have changed?

Who would have thought...

He is desperate for the peace prize and would happily negotiate anything at all on someone’s behalf without consulting them

The issue with giving up territory beyond the current front lines is that this would leave the Ukrainian fortified positions behind enemy lines and if Russia continues the war then there's nothing stopping them from advancing. That's why Russia doesn't want a ceasefire either because Ukraine would just use that time to further build up their current defensive positions making it even harder for Russia to advance in the future.
