What are you basing this statement on? All analysis I have seen so far come to the conclusion, that the war is devastating on an humanitarian and demographic scale, but sustainable for years to come from an pure manpower & training-capacity pov. (Given historical data)

The same analysts suggest that the main reason for the current stalemate is the lack of weapon systems/munitions, that would enable a sustained breakthrough like artillery, tanks and air defense systems. Stuff that western allies hesitate or are incapable to provide in large quantities.

You can’t ‘learn concepts by repetition’, that is not how learning works. You can learn a concept & repeat its application to be faster at it.

And that’s the problem. What if the student didn’t catch the concept during the lesson? He or She needs help by a guardian or be punished for not completing the task.

Same thing with the supposed self management skills. What if the student fails at it? He or she needs help by a guardian or will be punished.

At the end of the day homework is a tool to offload tasks of the school to the guardians of the student. A schools system, that relies on homework, is a system that fails in its task of creating a level playing regardless of socioeconomic background of the student.
