The way I read the situation is Ukraine is losing ground, ground that will cost them more lives to retake, they are grimly hanging on awaiting the weapons the west are promising, but are slow to deliver, and that is costing them in lives, civilian and military, but more importantly lives of their experienced professional troops, something they will struggle to replenish and that is the fault of the west.
I do wonder if anyone will ever buy tanks again from Germany or ammunition again from the Swiss because they have both shown their failings in all of this, the one advantage Russia appears to have is artillery and the ability to use it to pulverise cities, they need sufficient accurate longer range weaponary to take that on from a position out of reach of counter fire. They also need to be given a few long range HIMAR rounds to drop that bridge and cut off the resupply route.
Then they may have a chance, at the moment they are fighting a fight with one hand tied behind their backs.
