Bush acknowledges slavery in Iraq?

Bush's recent Executive Order allows the US Gov't to take assets from people who commit violence against the Iraqi government. The way I read it, the affected people are "any persons determined by the [US] Secretary of the Treasury ... (i) to have committed [violence], (ii) to have assisted [anyone covered by the order] or (iii) to be owned or controlled by [anyone covered by the order]."

So that Section 1 (a) (iii) seems to be broad enough to cover any slaves that may be owned by insurgents in Iraq. Is this some problem they haven't been talking about?
