> As for sources, IF they got enough HEU they could most certainly manufacture working gun assembly nuclear weapons; as usual the trick is getting the fissionables, but are you entirely, "You Bet Your Life" sanguine about Pakistan's control over its nukes and nuclear materials??? I will note that Manhattan Project scientists were so confident in the gun-assembly nuclear bomb, that they didn't even bother testing it (in the age before computer-aided design, no less!). The first working gun-assembly bomb was detonated over Hiroshima. In other words the first atomic bomb ever dropped in anger had never been test-fired, that's how confident the designers were that it would work. The real magic of the Manhattan Project had been the industrial-scale development required to piece together all that weapons-grade nuclear material in the first place, not the design itself.
