Putin has created a strategic disaster for Russia. With this catastrophic invasion, he has shown the world, especially China, that Russia’s conventional military is not the juggernaut the world once feared. Can Russia defend their rich but underpopulated Far Eastern Pacific territories and Siberia? Does it not make more sense for Comrade Xi to attempt to seize these Asian lands than attempt a risky invasion across 90 miles of open ocean? Without nuclear weapons, Russia would be much smaller.
Accepted military doctrine says that an attacker should have a 3-1 advantage over a defending force.
The Ukrainians had a 3-1 advantage over the attacking Russians & the Luhansk/Donetsk militias.
I'd say that the Western militaries have some doctrinal revisions to attend to.
“With this catastrophic invasion, he has shown the world, especially China, that Russia’s conventional military is not the juggernaut the world once feared.”
The big problem with you assessment is that it is demonstrably and irrefutably false.
Whoever takes on Goliath, and knocks him cold, will be *very* popular on the world stage.
