The problem is that the GoI whines and complains so much that inevitably any decision Pakistan takes will coincide with some event or the other, and then commentators will crow, 'AHA - thats what tipped the scales!'.
Someone might come out and say that it was Kapoor threatening war that did it.
Or maybe because Pakistan wanted to make a point by doing so close to the anniversary.
Or maybe because the Indian president scared us by flying in that Sukhoi.
Or maybe because South Waziristan is coming under control.
Or maybe because Zardari wants to deflect attention away from his domestic political problems.
No shortage of coincidences and events you can weave a conspiracy theory around.
