Well that's my point, we all know Pakistan got its major nuclear equipment through black market & for that a network had to be setup & once a setup is made they start doing business with other buyers too. Iraq got a lot of its nuclear, biological & chemical weapons equipment & raw materials from European countries through European or other western firms & agents, meaning western countries have themselves black market businesses or westerner guys doing such business as to them money matters, not whom it goes.
Also, if the govt knew what he was doing, what is the assurance that the money went into his pocket not the govt guys who knew what was happening or to the nuclear program itself ?? How can we belief the Musharraf govt version or the American govt version that he got the money for himself. If he had, where is the money, his accounts should have been blocked by now or details told. The govt already blamed him for everything to be running this network all by himself, definitely they gonna say he got all the money too. Most of that money may have gone into buying new equipment or pumped into the nuclear infrastructure.
If we look at history, whenever governments or organizations have been behind such kind of illegal activities, like drugs or things like that, they get their cut too or use that money for other activities.
We just know the govt version of the activities, not the real secret. Govt would do anything to save its arse.
