This is the best assessment of the current pull-out of uniformed US troops from Iraq that I have seen.
In Iraq itself, uniformed troops are being replaced by a new army in civilian clothes. A massive, fortress-like American embassy in Baghdad has been erected in a walled compound of 104 acres—larger than the Vatican—with two similar facilities having been opened as consulates in the southern oil center of Basra and the Kurdish capital of Arbil in the north.Meanwhile, according to this report, the Empire's weapons industries look forward to big profits from selling weapons to the Empire's satrap in Iraq.
Operating out of these American fortresses will be up to 17,000 personnel. They will include 5,500 armed military contractors.
