It's their own righteous cause and they continue to fight so they think it's worth it, yes. If the people actually wanted to give up they'd say so.

Who are you to decide such things for them?

When the Taliban rolled over Afghanistan I wasn't there, saying "But you should fight for your freedom!" -- nah, people have to want it on their own accord. In that case all I could was to throw up my hands in despair, seeing a country fall from occupation into tyranny. Ukraine? Least I can do is defend it morally against vulgar pseudo-pacifists like you, who'd rather see Ukrainians brutalised and exploited by the Russian Mafia.
