What happened to Iraq’s army?

“The whole issue of Iraqi soldiers — how many died or were wounded, how many deserted or fought to the end, where they are now — is surrounded by a veil of secrecy. Neither the U.S. forces in Iraq nor the Iraqis themselves seem to be willing to delve into it too deep. As a result, conspiracy theories about Iraq’s defeat, involving either treason or the U.S. use of ‘low-level nuclear devices,’ abound.” Salon
