Maybe this story, while possible, is more likely - bunk.
The WTC bombings took a decade to carry out.
I don't know about the shelf life of nukes in suitcases.
I do know that many of the sources, and the statements from them, and much of the data that he sources is compelling and that I myself have read much of the same data.
Don't shoot the messenger.
Maybe they're waiting for the Chicoms to pre-position troops in Panama and Nassau for the invasion after the nukes are lit? <[8-) (wish i could make a better tinfoil hat symbol)
