The Russian military would have to redeploy units from inside Russia, and that means transporting them and supporting them when they arrive. Putin has not ordered a general mobilization, and their recruitment efforts amount to finding cannon fodder to fill body bags. Unless the Russian Army is willing to draw real units from inside Russia, sending their recently recruited forces will just get them killed.
If Russia has a way out I have no idea what it is.

If you were Comrade Xi and duly noted the performance of the Russian army what would you be more likely to do? Would you attack a well defended Taiwan across 90 miles of open ocean? Or would you be wondering if all those locally produced ships ,planes and huge army of China, though combat untested, have the ability to seize Russia’s rich, underpopulated Far Eastern Asian Pacific territories and the treasure house of Siberia.
Suspect if Russia did not have nuclear weapons, it would be much smaller.
Interesting...Time will tell...
