The uranium thing is a bit of a red herring. Having some U is one thing; refining it to weapons-grade and designing the bomb itself is another entirely. A lot of countries have radioactive materials, but few have nuclear weapons...and for good reasons.
The most credible scenario of terrorist use of uranium is that they use it as a poison, actually.
Correct, Mr. Jr. U-238 contains a bit of U-235, which is needed to make an atomic weapon. However, only a fraction of 1% of U-235 is in U-238, and it is a BITCH to refine it to get appreciable quantities of U-235 to make an atomic bomb. See http://serendipity.magnet.ch/more/a...ml#development.
Weapons-grade plutonium can be manufactured in a nuclear reactor, but only at such small quanmtities at a time that it would take several months to even get mere grams. And the reactor fuel that is sold around the world to other countries for their nuclear reactors has been processed so it is not weapon-grade type of fuel (i.e. it cannot be used to make explodable plutonium).
Even if you could make enough weapon-grade plutonium for a bomb, it must be milled precisely smooth & round, and be triggered by high explosives in such a way that equal pressure from all sides of the round ball of sub-critical mass to make it implode in such a way that it will reach criticallity and go boom.
The refining of both uranium and plutonium would take so long, and the facilities so large and expensive, that it would be impossible to hide it totally from the prying eyes of modern nuclear capable nations like the US (and the US is always watching for signs of these things around the world). In fact, Israel blew up an Iraqi reactor in 1981 precisely because it was a type of design capable of manufacturing weapon-grade nuclear fuel.
For an in-depth story about nuclear weapons, I suggest reading "The Making Of The Atomic Bomb" by Richard Rhodes, available at fine bookstores everywhere. It is a very good book that will explain everything you would want to know and more about this subject.
