Al-Qaida in Iraq: 4,000 foreign fighters killed

The new leader of al-Qaida in Iraq purportedly said Thursday in an audio message posted online that more than 4,000 foreign militants have been killed in Iraq since the U.S.-led invasion in 2003 — the first apparent acknowledgment from the insurgents about their losses.

To my all honesty, I really dont know why they're doing it. They said

It was unclear why al-Masri would advertise the loss of the group’s foreign fighters, but martyrdom is revered among Islamic fundamentalists, and could be used as a recruiting tool. The Arabic word he used, “muhajer,” indicated he was speaking about foreigners who joined the insurgency in Iraq, not coalition troops.

I don't want to speculate too much, but the declassified part of NIE just said Iraq war is fueling anger against America. No implication here.
