I think that was significant. In fact, given that those individuals are probably the best educated, well trained and, therefore, most likely to find employment in other countries, that represented a significant loss. At the same time, it probably reduced some of the sources of internal pressure on Russia.
A lot of the recruits for the Russian forces are coming from distant provinces, different towns. They're not sending the sons of the elite middle classes in St. Petersburg and Moscow into this war yet. That would change things, possibly.
One aside I want to make here very quickly is that we're talking about human resources and trained human resources. Finding a way to usefully employ and exploit that exodus from Russia is something we should be paying very close attention to. These are people who have made personal decisions to avoid the draft. They have pulled up their roots and left the country. That is a potential resource. I'm not talking about giving them rifles and sending them into the front in Ukraine, but that is a significant resource that could be useful to the west.
