You can laugh for all you want but the fact of the matter is that it is Pakistan's credibility which has taken the hit.
Are you sure? Doesnt seem like anything has changed. Pakistan has done its bit, they have closed the offices of Let etc. So what else is new? The world has moved on.
Last I checked, it was India that has been nervous lately. First it was Miliband claiming Indias Kashmir problem is the source of all this, and now even Obama is saying he will focus more attention there, to the dismay of Indians ofcourse.
And did you happen to read the article? Most people in India doubt the credibility of Indian police accounts. Indians themselves have questioned thier statrs credibility.
