you do understand that India's defence expenditure is 5 to 6 times more than Pakistan, so unless Uncle Amirkhan is going to be paying $20 billion /yr, uncle can't bridge the gap.
In fact the US need not do that. All it needs to do is a well timed injection of arms into Pakistan.
Sending in 24 F-16s, 1000 AMRAAMs, 500 Harpoons and sharing intel info from US satellites would help inflict enough pain on India in a war to put warlike thoughts further out of Indian minds.
I think that anyone who is not fully convinced that the US wants to play its own game in its own way needs to understand that every country uses intel assets to achieve goals. If India wants to attack Pakistan in any way all preparations have to be hidden not just from Pakistani eyes but US eyes as well. the US knows India will be doing that and will be watching India very closely. This whole 'cold start" business is to finger the US as much as Pakistan.
Wars are intel dependent. The Longewala battle is a classic case in point. The presence of Paki armor across the border from Longewala was missed/ignored. When the Pakistani attack came there were insufficient Indian ground forces to check the assault. But the timely use of air power tilted the balance in India's favor.
Imagine a situation in which things are hotting up after a terror attack. The US informs Pakistan of the whereabouts of Viraat and Pakistan sends two subs that box the Viraat in. India initiates a thrust into Pakistan and is getting ready to start another thrust in another area when US intel info is passed to Pakistan which is able to fire missiles and conduct airstrikes on an Indian armored build up, while US AWACS assets are used to "blind" Indian radar.
This is exactly the sort of behavior that the US (and its allies) have resorted to in various wars.India's ultimate aim will have to be to hold Pakistan and help bring the US down. There is no other go. It is a dog eat dog world and anyone who expects anything good from the US is either mistaken or is not a nationalist
