This was just a message.... the meaningful steps will be to vote "no" to proposals that ask for additional funding of the war.
The big debate will be whether cutting funding means leaving our troops hang out to dry or if it only forces us to set a timeline for withdrawl before the current allocated funds dry up.
We will hear about this debate in the press ad nauseum for months. I suppose if we want to be active citizens, we can write our representatives about how we feel about the legislation when it is proposed.
