Bush administration lawyers claim that there’s no need to consult Congress about attacking Iraq, since the 1991 Gulf War resolution is still in effect. Never mind that the resolution was passed in response to Iraq’s invasion of Kuwait, or that the Gulf War seemed at the time to have ended with the April 91 cease fire.
It’s true that the lines of responsibility for starting wars are mightily tangled; administrations and Congress have been fighting over the power to start wars for the whole of US history.
But this argument is completely absurd. It makes one suspect that the proponents consider democracy a bureaucratic inconvenience.
