BY nothing, they meant chemical weapons folks. The white powder is the high explosive that the NYT is so up in arms about. Go to Kerry spot and read this article and be informed.........the 'high explosive' the ny times is refering to is not 'plastic' explosive, or even something that you can easily blow up. It is a chemical which, when combined with other chemicals, can be made into things like c-4, etc. This article doesn't prove anything....................this is what the stuff is..............A key point is that this is not dense stuff, where you can get a lot of weight into a small vehicle. If this was really in its raw form, it is white powder, like cornstarch or a light powdered sugar (NOT granulated sugar). Blow on it and it flies in the breeze- the stories I've seen haven't said much about what form it was in, but you would want it to be relatively raw so you could form it into main charges for artillery, etc. They don't pour granules into shells, it is mixed with binders and melted sonit will take a shape. You can't be a nice terrorist, happen by, stick some in your pocket, and run away while the US Army isn't looking- it isn't "plastic" (like, say, comp C4, which is a plastic matrix impregnated with HE, thus has a lot of filler to make it shapeable). The kinds of trucks you would need to haul it are like grain hoppers, and lots of them. You can't stack it on pallets.
I think what we are getting at is the fact this has been known for over a year.
The "white powder" was not the 380 tons of HMX and RDX.
