One the thing that is called the green Zone is a very protected area arround Bagdad where we have bases. Some hotels there I believe. I don't know how big it is.
Forget about the bases. I got that part wrong:
"The International Zone (formerly known as the Green Zone) is the heavily guarded area of closed-off streets in central Baghdad where US occupation authorities live and work. The Green Zone in the central city includes the main palaces of former President Saddam Hussein. The area houses the civilian ruling authority run by the Americans and British and the offices of major US consulting companies.
The precise boundries of the "Green Zone" are difficult to determine, and indeed may change with time. The core of the Green Zone appears to be the presidential complex of Saddam Hussein. "
Oh, of course. Thanks Revel.
