Using the G Word

The G Word.
Been meaning since Thursday to give credit where due: Powell's statement that the United States views the killings and rapes in the Darfur region of western Sudan as genocide was the right move. It puts some significant weight on the Security Counsel as well as the US. As our foreign policy is, for now, in a paradigm shift of sorts due to the new Bush Doctrine, what does this genocide label mean as far as US military action. We invaded Iraq due to, as the current reasoning goes, past genocide. Are the ramifications for current genocide the same?
