not true. Russians injured a bunch of american troops in syria with no significant response from the u.s. the fact of the matter is that just as the u.s. and Russia won't risk a nuclear escalation, China won't either so they took an escalate-deescalate-reescalate approach with india, basically death by a thousand cuts, drain them in the long run while hitting their economy...india's dirty little secret is that with the risk of a nuclear exchange with a huge power like China, investments were fast leaving india which was one of the driving factors for india to fold and accept China's 1959 LAC. the harsh reality is that india is not conventionally strong enough to even handle a nation 1/6th its size like Pakistan, you think they stand a chance against China? no they don't. india's only fallback is nuclear, so even though China would've ripped india an even bigger bunghole, they can't risk a nuclear escalation. don't forget, there isn't an ocean seperating China and india and india has a way of panicking and reach for the red button.
