Austin Bay is a frequent writer on matters military. Today he predicts that China - which has caught the same empire rebuilding virus that affects Russia - is likely to want to invade Siberia, which it (a) covets and (b) believes for historical reasons is rightfully theirs.
If Putin goes all in on taking Ukraine he doesn't have sufficient reserve forces to protect Siberia against a bulked-up PLA. Col. Bay suggests Trump remind Putin of this vulnerability.
Russia's inability to defeat much smaller Ukraine suggests their military is less formidable than previously thought. You can be sure Beijing has noticed this weakness.
Being "the leader who lost Siberia" isn't the historical sobriquet Putin craves for himself. I had this same insight four decades ago, as I noted in this post about a long ago game of Risk™.
