Nope, a constitutional republic.
The part of the Constitution that talks about Congress declaring war was repealed?
Nope, Congress declared war in a manner they chose by authorizing the CIC to execute war on Iraq if warranted. The CIC deemed it warranted and exercising the authoirty granted him by Congress, in turn authorized the military to wage war on Iraq.
All very constitutional.
So, Congress can ignore their constitutional duty and pass the authority to declare war to someone else? That's like saying they can pass a law making someone king and calling it "constitutional."
