Collapse is best observed from cozy apocalypse-equipped armchair. China periodically breaks apart and reunites for 2,000 years plus, since the times of Qin dynasty fall and Chu-Han clash; I think even the least competent Western analyst can’t be expected to seriously consider possible future Chinese collapse as final. Ditto Russia. It can exist only under the imperial aegis, which is not good or bad per se, but simply most logical from the PoV of its historical evolution, marked with oscillations between cosmopolitical and autarkic attractors.
