They're losing the war at a rapidly increasing rate. But they have to spin it as a victory. They've been claiming this entire time that the Russians are throwing massive amounts of men and materiel at them in human waves. It makes sense to keep using that claim and say that Ukraine is cleverly exploiting the dumb Russian tactics to increase the attrition rate.

Of course that all falls apart even if you only read western media, if you read further than the headline. The reality is an underequipped, under trained, under staffed UAF being sent to the frontline in their mass. Pretty much the opposite of what's advertised. You're not supposed to remember that Russia has air superiority and at least a 3:1 advantage in artillery and drones. You aren't supposed to see the military cemetaries in Ukraine adding hundreds of thousands of new plots.

You're just expected to forget all that, and believe Zelensky when he says that there have been less than 40k casualties, and Russians are throwing themselves on the brave Ukrainian bayonettes. Then this makes sense.
