NO SE SABE AÚN QUÉ HABÍA en esas caravanas de camiones, pero da que pensar, y mucho:

Saddam Hussein periodically removed guards on the Syrian border and replaced them with his own intelligence agents who supervised the movement of banned materials between the two countries, U.S. investigators have discovered.
The recent discovery by the Bush administration's Iraq Survey Group (ISG) is fueling speculation, but is not proof, that the Iraqi dictator moved prohibited weapons of mass destruction (WMD) into Syria before the March 2003 invasion by a U.S.-led coalition.
Two defense sources told The Washington Times that the ISG has interviewed Iraqis who told of Saddam's system of dispatching his trusted Iraqi Intelligence Service (IIS) to the border, where they would send border inspectors away.
The shift was followed by the movement of trucks in and out of Syria suspected of carrying materials banned by U.N. sanctions. Once the shipments were made, the agents would leave and the regular border guards would resume their posts.

Habrá que ver qué dice Charles Duelfer, el jefe de los inspectores, en su próximo informe provisional de Septiembre.
