As I said....Putin might have miscalculated this time....this could be the one step to far!
Or, we in the West are miscalculating and misjudging this whole thing.
I think we make a mistake by not coupling this with China.
Russia and China have grown closer together. Russia sees China as a stable and reliable consumer of its coal, oil, and arms. Plus, China shares the same geopolitical goal as Russia: to weaken the US (yes, I admit I have a USiancentric POV, but it is true from what I can tell). A weaker US means a weaker NATO, and that's Vlad's major concern with the Western world; he wants that buffer on his western border.
Vlad's Ukrainian play is useful for China. It puts more stress on the US, thereby creating a more malleable environment for China to make even more bold moves in SE Asia. Xi may see a favorable opening to finally move on Taiwan. A move on Taiwan now creates a crisis not only for the US, but its allies. This could be seen as the most opportune time for China to actualize what it believes it is: the rightful center of global power.
I fear as we play checkers, the Chinese (and to a much smaller degree, the Russians) are playing chess.
I'm not convinced these sanctions are going to have the teeth we are hoping for.
Hopefully, I'm just batsh!t crazy and way off the mark.
