This is why I prefer to ignore Ignorants. There's no point. US gives India access to their full ISR capabilties in the region for what, just to stare at each other? Such real time access is unnecessary if there is no military goal.
In a Sino-India war, merely using targeting coordinates from a USN sensor to attack a Chinese vessel using an Indian weapon is still an act of war by the US, as long as the Chinese find out and challenge it. If they don't, then anything goes.
