The trail that investigators have uncovered, partly from reading computer hard drives found in Baghdad and partly from interviews with captured members of Mr. Hussein's inner circle, shows that a month before the American invasion, Iraqi officials traveled to Syria to demand that North Korea refund $1.9 million because it had failed to meet deadlines for delivering its first shipment of goods.

So you get 'Potemkin weapons'; reports, promises, trailers filled with impressive-looking technical equipment, UAV's that are really just oversized model airplanes. Occasionally, some competent or especially frightened technician might actually produce something - but almost certainly not on the scale that the dictator believes. So Saddam believes he has them, and from that, we infer that he does, and what is really going on is a bunch of nervous paper-shuffling.
