Pakistan openly sold nuclear technology

From Janes Defence Weekly:

When Pakistan opened its first international arms exhibition in the port city of Karachi, something was amiss. It was November 2000 and there, among defence industry stalls offering tanks, missiles and rifles, was the booth of A Q Khan Research Laboratories (KRL). The display contained a range of conventional military products, including defence electronics and anti-tank missiles. However, KRL is also a top nuclear weapons laboratory and its employees were distributing stacks of glossy brochures that promised technology for producing a nuclear bomb.

And:

Several KRL officials provided positive assurances that all had government approval for export.

The cat may already be out of the bag.
