To be fair, NATO can't use the bulk of their airforce because they still fear escalation. Even though 40 years ago, Chinese and Russian fighter pilots had 0 issue massacring US planes in a proxy war and US never responded to this red line being crossed, for some reason beyond me, NATO believes Russia will. Or theyre that scared of China overtly going in.
Crazy thing is Russia only has a small fraction of China's actual tech or production capability. They're getting some subsidies, but not the whole or even a signficant portion of PLA kit.
If there's a major war in Asia (which I'm not sure will actually kick off due to CPC focusing on peace through strength), we will with most certainty see a paradigm shift in warfare.
