With the nuclear deal between India and US set in stone, India now has access to US civil nuclear technology. This will without a doubt, give India a much needed boost to its nuclear weapons programme. Pakistan and China are of course quite unhappy about US' move, but such is the fickle world of politics; where allies can be gained and lost in a blink of an eye.
Unfortunately, this deal might very well ignite the nuclear arms race in Asia, destabilising country relations in the process. Perhaps this is also America's way of pressurising Pakistan to cooperate with them to eradicate the Taliban? The Taliban has always been a thorn in the flesh for the folks at Washington, and Pakistan's on and off relationship with the Taliban certainly doesn't alleviate the situation. The rise of India is worrying the Pakistani officials, and with this nuclear deal, Pakistan has to think carefully on how to navigate her way to a future where her sovereignty will still be respected.
