http://www.newyorker.com/printables/fact/070305fa_fact_hershRE: General Pace's testimony before the Senate Appropriations committee yesterday - Pace is saying one third of the total military force in Iraq will not be fully manned, fully trained, or equipped AND he (**Cheney**) doesn't want Murtha to do anything about that.
Pace also said before the Senate Appropriations Committee that a weak Iraqi government (Shia) results in stronger militias (Sunni). The "Redirection" documented by Seymour Hersh (linked above) describes a process that is weakening Shia in the region and strengthening Sunnis.
So, as the Sunni Iraqi militias get stronger they have to decide whether to kill more Americans or more Shia. Doesn't the fact that the Administration is resisting Murtha's plan, and thus leaving those forces weak in that situation, suggest that this is supposed to push the Sunni Iraqi militias in the direction of attacking the Shia instead?
It's the old "Bait and Switch" routine again. Only this time it is American Blood being waved under the noses of the Sunnis in the region to get them into what's going on, and then through the use of special Sunni operative$$$$$$$$, their efforts are turned on the Shia instead.
