The Russians and the Chinese have the same approach to war that they have had for centuries. Any cost, human or otherwise, necessary to win is an acceptable cost. The only time that wasn’t true was in WWI, and that was only because Lenin and the Bolsheviks figured it was worth losing the war in order to ensure the revolution—even 100 years ago, the issue was never the issue, the issue was always the revolution.
(Lenin and the Bolsheviks, sounds like a Marxist pop band)
Which is funny/ironic because NATO is using its totally controlled colonial government in Ukraine, and its cannon-fodder citizenry, to fight a proxy war on its behalf, which will end up completely destroying Ukraine.
