The Ukes should have emulated George Patton - “ATTACK, ATTACK, ATTACK!”
Patton had one of the world’s strongest armies at that time, and his side was getting stronger while the opposition was getting weaker.
The Russians started this war as hands-down “they’re going to win” - like the US basketball dream team of the 1990s facing off against a Manila high school team.
But the Russians lost. And lost badly.
However, the Ukrainians don’t have enough to attack further. They did a great job defending. Now they need artillery to push the Putinistas out of the Donbas
