The Russian people are killing themselves. Crashing birthrate, highest abortion rate in the world and those who can get out are quitting the country. In 50 years, the Russian people won't exist in any meaningful way.
Driving Russia away from The West drives Russia further and further into the deadly embrace of China. That accelerates the problem of the growing power of China.
The only people with worse demographics than the Russians are the Chinese.
Imagine China with control over Russian land and Russian natural resources.
The goal is to bleed Russia dry, control their inevitable collapse, get rid of the nukes they have pointed at us for 60 years, and then control their resources for ourselves.
Russia is being handed to China on a silver platter.
