How Would We Have Known That?

Did the Baghdad briefers screw the pooch on Sunday and reveal something that was obtained through national technical means?

Maybe that's why Gen. Pace is walking back the assertion.

Marine Gen. Peter Pace, chairman of the Joint Chiefs of Staff, said yesterday that he has no information indicating Iran's government is directing the supply of lethal weapons to Shiite insurgent groups in Iraq.

"We know that the explosively formed projectiles are manufactured in Iran," Pace told Voice of America during a visit to Australia. "What I would not say is that the Iranian government, per se, knows about this."

"It is clear that Iranians are involved, and it's clear that materials from Iran are involved," he continued, "but I would not say by what I know that the Iranian government clearly knows or is complicit."

Pace's comments came a day after U.S. military officials in Baghdad alleged that the "highest levels" of the Iranian government have directed use of weapons that are killing U.S. troops in Iraq. No information was provided to substantiate the charge. Administration officials yesterday deflected requests for more details, even as they repeatedly implied Tehran's involvement. ...

Sunday's briefing on Iran, originally scheduled for last month, had been delayed as officials said they were trying to avoid "overstating" what they could prove.
