"This ominous discovery, unreported until now, makes it clear that Iraqi insurgents have no need to rely on Iran as the source of EFPs. The truth is that EFPs are simple to make for anyone who knows how to do it. Far from a sophisticated assembly operation that might require state supervision, all that is required is one of those disks, some high-powered explosive (which is easy to procure in Iraq) and a container, such as a piece of pipe. I asked a Pentagon analyst specializing in such devices how much each one would cost to make. 'Twenty bucks,' he answered after a brief calculation. 'Thirty at most.'"
Compare this unsourced assertion to that of the anonymous military official in Baghdad last Sunday. As reported in the New York Times:
The precise machining of the EFP components, the officials said, is another feature that links the weapons to Iran. "We have no evidence that this has ever been done in Iraq," the senior military official said.
Regardless of whether or not the anonymous official was lying when he said the US had no evidence of EFP's being made in Iraq, Cockburn makes a good case that the production is not as complicated as the military "experts" made it seem.
