It is difficult not to sympathize with Zelensky's desperation in a war that is indeed going badly. However, at some point, cabinet reshuffles and resignations will not suffice to deflect responsibility for decisions that have made it even worse.
Honestly Putin / Russia is going to be victorious. The only way to prevent that is direct Western intervention and that shouldn't happen as it would escalate.
Better to lose a country to Russia than the world for everyone.
