What I think US could do however is give us aerial recon and AWAC support if at all they would want to get involved in Indo-China conflict. They would have to operate the AWAC while our fighters would receive real time info through datalink. India and US have done excercises (both Navy and Airforce) to work out the modalities and integration issues to be able to jointly coordinate in operations. I dont whats the current status and how far we have actually progressed on sorting out integrational issues but my guess would be we have fair amount of capability to jointly coordinate in military operations.
But we would still require their (US) direct involvement, not just their equipment, in order to jointly coordinate. The question is how far would they want to get involved.
I think the stakes for the US are higher in a China vs India situation than in a China vs Taiwan situation. Even from a toe-hold in the Indian ocean situation, it will be worse off for the US should China start to push downwards into India.
