EFPs easily made in Iraq, so who needs Iran?

Via Kevin Drum, I find this piece in the LA Times:

PRESIDENT BUSH HAS now definitively stated that bombs known as explosively formed penetrators — EFPs, which have proved especially deadly for U.S. troops in Iraq — are made in Iran and exported to Iraq. But in November, U.S. troops raiding a Baghdad machine shop came across a pile of copper disks, 5 inches in diameter, stamped out as part of what was clearly an ongoing order. 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."

Seems to me that sucks all the air out of the administration's bloviating.
