This is hardly a Russian talking point. Russia does not want more Ukrainian soldiers.

The entire neocon press makes the point that people are evading service:

I don't blame them. That's why it would have been better to accept the Istanbul agreement while Ukraine had the upper hand. Naftali Bennett (hardly opposed to wars in principle) said that this agreement was sabotaged by the U.S., but he walked back that statement later.

I do blame Ukraine for not holding elections and finding out what people really want.
