I do not believe that cutting off support to the Terrorist-Harboring Majority Government of Iraq (and, yes, Virginia -- Al Dawa IS in the Majority Coalition; heck, the Prime Minister of Iraq is from Al Dawa party!) will necessarily hurt their minority political rivals (the alleged "good guys").
Put simply, it is often the case that removing support from one rival, helps the opposing rival (becuase now his opponent has less financial support, etc.)
This may not always be the case, but I think it is at least as likely as your argument that Militarily and Financially supporting the Terrorist-Harboring Majority Government of Iraq somehow helps their minority political rivals!
The Sadr folks in Al Dawa are moderates in some ways compared to the other main party in the government, SCIRI led by Al-Hakim and his Badr organization.
"as your argument that Militarily and Financially supporting the Terrorist-Harboring Majority Government of Iraq somehow helps their minority political rivals!"
That is not my argument at all, it's yours. I thought the coalition was supporting an environment in which the principles of Democratic Freedom could take hold. This means supporting Iraq (not just the government, I never said that) so the political debate can take place.
Supporting an environment that will foster a political debate towards Democratic Freedom is not the same thing as "supporting the Terrorist-Harboring Majority Government of Iraq". You must look at it this way to advocate removing all military and financial support from Iraq. It is your choice to view it that way but that is a simplistic and wrong way to look at it in my opinion. Our financial and military support covers a whole lot more more than just the Iraqi government, I think it is dishonest to imply it doesn't.
