Re: DAM AK-47 are from 1947.
Ah, but these are not EU Glocks. (Why should the EU give out Austrian produce in a US-occupied territory). To cite:
The author of the report from the Government Accountability Office says U.S. military officials do not know what happened to 30 percent of the weapons the United States distributed to Iraqi forces from 2004 through early this year as part of an effort to train and equip the troops. The highest previous estimate of unaccounted-for weapons was 14,000, in a report issued last year by the inspector general for Iraq reconstruction.
But yes, quite certainly these were sold on. This is why Obama's proposal to ship weapons to Syria overtly (and prior to that, one suspects, covertly ship the contents of the armories of late strongman Ghaddafi via CIA express) is not necessarily the best idea. ISIS now has 2 billion cash to spend.
