It seems like your frustration that Putin's failed 3 day war, now in it's 3rd year, not going to expectations is building.
Opinions like "Not sure why Zelensky insists on continuing a war he can not win" when the fact that Putin's forces have suffered massive, humiliating defeats on several fronts show that Ukraine is very capable of defeating Putin's invasion and occupation forces betray a level of frustration that things are simply not going as you expected.
Putin has been trying now for more than 10 years and he has not accomplished a single objective, in fact with one of his objectives of preventing "Nato expansion" he is sitting at -2, he no chance of accomplishing a single objective means the conversation should focus on Putin ending his failed war against Ukraine and not on pro Kremlin propaganda narratives that Ukraine cannot win.
Ukraine was invaded in an unjust and unprovoked war by a fascist murderous imperialist war criminal regime, they have every right to defend themselves against that unjust and unprovoked invasion and the West has every right to help Ukraine in their decision.
