I understand your howling, a hit dog always does. But I don't believe America will sit still if India were happened to be attacked from either Pakistan or China. Remember also, 9/10ths of technology's success comes in the ability to use it.
Still, it was a dumb move to equip the Paks with the AC's.
You will be the one howling when Pakistan pulls an Iran on you guys.
As for American help, I wont be so sure nor would I want to count on US help.
