In this angry editorial, the Nation accuses the Nuclear Suppliers' Group (NSG) of discrimination against Muslim countries, specifically Iran and Pakistan. The focus of the editorial's ire is the recently concluded civil nuclear agreement between Canada and India.
Pakistan's anger is misplaced. Pakistan's treatment can be attributed to the actions of one man: Abdul Qadeer Khan. Google for details. Suffice it to say, Pakistan, through Khan, sold nuclear technology to anybody who wanted it, as long as the price was right: North Korea, Libya, and Iran. No wonder the NSG is so suspicious of Pakistan!
In addition, why does Pakistan seek these nuclear deals when its patron -- China -- will give Pakistan whatever nuclear technology it wants? Sour grapes would be my guess.
It's all about status. Pakistan delusionally believes that it is an equal to India in all respects: hence what India gets, Pakistan should automatically get. This is all nonsense, of course; and the reasons are obvious.
