While the amount of spending money has an effect, wisely spending the money pre-war and wisely executing war plans is obviously critical. Russia is demonstrating the weakness from widespread corruption (they got stuck on roads because they did not invest in logistics and on maintaining their vehicles), combined with spectacularly poor planning in the initial attack. It would be unwise to assume China will make such mistakes.

Anyway, it is my hope that war does not break out. The one guarantee about war is many deaths.
