This seems to be the sad realpolitik truth. It explains how some of the aid has been given.
Enough to keep grinding down the Kremlin’s war machine, not enough to actually take the Kremlin out of the fight.
In a more utilitarian analysis, this might be the best for the greatest number of people. From an empathetic human perspective… it’s pretty fucking dark to see young Ukrainian men dying for this. Still better than living under the Kremlin’s boot.
