It sounds like a mixture of truth and sensationalism. One shouldn't judge a book without reading it first, but I would receive this one with caution until having a closer look at it.
I'm a bit troubled by the description of the author at Amazon:
"Paul L. Williams, Ph.D., is a journalist and the author of The Al Qaeda Connection: International Terrorism, Organized Crime, and the Coming Apocalypse; The Vatican Exposed: Money, Murder, and the Mafia; and Osama's Revenge: The Next 9/11—What the Media and the Government Haven't Told You. He has served as a consultant for the FBI, as editor and publisher of the Metro in Scranton, Pennsylvania, and as an adjunct professor of humanities at the University of Scranton."
As I said, a lot of this sounds reasonable. But does al Qaeda have nuclear weapons already? Maybe so, but we've seen Soviet suitcase nukes before. If they have them, why haven't they used them?
And The Vatican Exposed: Money, Murder, and the Mafia?
Where's the grassy knoll?
As I mentioned, i've read the whole book...couldn't put it down...it is EXTREMELY meticulous and well-cited/documented
Al Qaeda purchased thirty million worth of nukes from former Soviet Union as it fell and became a third world nation overnite...also purchased a lot of radiological material...some of this material would act as a 'bone sucker'...gets into your bone marrow and gives you the symptoms of radiation poisoning...you can't 'clean' it you have to pretty much bury everything to get rid of it
2 British intelligence officers posing as muslims from a London mosque infiltrated Al Quaeda, swore 'bayat' (loyalty to the cause) and saw the facilites staffed by nuclear scientists
Osama has special teams trained in handling nuclear materials...
