@Oscar, I have no doubts about the possible financial benefits this would accrue to Pakistan, and China. Everything fine about that; but that economic benefit was always a sideshow to the strategic entanglement that Pakistan sought with China against India. Is that a wise decision in the long run though? is it a good idea to push India this hard against the wall?
It's always been talked about the paranoia the relatively weak, small, insecure Pakistan has vis-a-vis India. Now Pakistan and China will have to bear the paranoia of a relatively, even if temporal, weak India scared to death of a combined, co-ordinated attack on India from two fronts.
There has already been a very visible response (facilitating change of regime) to Chinese moves in Sri Lanka by GOI after the submarine docking incident. And that was almost certainly the least aggressive move considered. In the same breath, you can be certain that barring a miracle, an intervention in one way or another is inevitable in the Maldives. What these moves mean is basically that India feels terrifyingly threatened.
This might be cause for celebration at GHQ Rawalpindi, and ISI HQ in the short run, but such fear will undoubtedly manifest itself physically in one way or another, in a way Pakistan's fears found manifested in its aggressive foreign policy. The difference is that with India, the scale and magnitude ratchets up dis-proportionally. And in this, First nuke policy of PA may actually serve India.
