The Indian Strategic Command is led by a 3 Star General [1] so the position mentioned in the article that the police failed to find anything is load of BS. This type of stuff is taken care of by Intelligence agencies, and if there was anything extraordinary here, the repercussions must have reached this side of the border, i.e., Pakistan.
In fact, I find this whole mentioning of Pakistan twice in the article offensive. If there was even a whiff of Pakistani intelligence work here, the whole world would have erupted.
Actually, Pakistan is mentioned once in the context of being a possible suspect, as are the USA and China. The other mention is to state that only the Pakistani media initially took an interest in the death of one scientist, which is hardly some kind of negative accusation.
To add to this, it would not be in India's best interest to publicize any security issue within its nuclear complex.
Especially if that information would inflame a nuclear neighbor, with which there is already confrontational history.
I am also not sure how mentioning a competing nation that has been in direct dispute with the target nation is offensive, specifically in the context of listing nations that may have interest in the issue.
Why is it offensive? You seem pretty aware of the history there.. if it's foreign spies, ISI has to lead the list of possible suspects, right? They've got the motive, means and a history.
I'm American and I wouldn't be upset at speculation that the US was killing Iranian nuclear scientists. I'd be like "Well, yeah, it's always a possibility".
In fact, I find this whole mentioning of Pakistan twice in the article offensive. If there was even a whiff of Pakistani intelligence work here, the whole world would have erupted.
