My point is that the Russian people have a capacity for self-sacrifice that shouldn't be underestimated, especially when their (perceived) sovereignty is threatened.
During WW2, for example, the Soviets lost a total of 20-27 million dead. Only China, a country almost three times as populous, came close at 15-20 million.

The British Empire lost less than 500,000.
