The Russians may not expect such a fight in their future. Against lesser foes, this would be formidable.
Do believe that the Russian strategists know that eventually and inevitably, they will have to defend Siberia and their Pacific coast from China. Yet the distances and persistent gaps in Russian design and manufacturing is a huge problem for them. Not their courage, the Russian people have demonstrated amazing qualities under the most dire of conditions. Yet if they were smart, under Biden there will be many unemployed American designers and engineers with arms experience. It may sound traiterous to some but America’s long term interests would be well served if the Russians hired that talent to modernize their arms industry for their coming fight with China.
