Ukraine has no troops, no leader, no money. The war has been over for six months. Russia is just taking its time mopping up.
You have a distorted view of the war. Ukraine has been holding Russia off for three years. The Russians have suffered huge casualties in men and material for minimal gains. Their money is running out and now Ukraine has been hitting them in the heart with its attacks on refineries. All is not rainbows and sunshine is Russia as you think. The Russians need more than just “mopping up.”
