"getting sufficient pure U or PL is not easy. "
Oh, you can get quite pure uranium all right - just dig around in shell craters in Iraq. The problem is that it's the wrong kind of uranium, and it's the extraction of the 235 isotope that, fortunately, presents a difficult problem. If anyone ever invents a simple, cheap means of isotopic separation, goodbye civilisation. A gun-type uranium bomb won't, however, fit into any guided missile whose construction wouldn't attract a lot of attention. Those things are big.
Fortunately too, not only is Pu hard to obtain, it's hard to make it into an effective bomb.
