The Bush administration has essentially declared unilateral capacity for war. They can use military power in any way they choose with no jurisdiction under the American people's congress. Who do they claim they stand under? The UN and international bodies. 99% of the world's military power that is the US is under international jurisdiction.
As we speak, the NSA/FBI is being dispatched to watch everyone across the US.
We have been in martial law since 2001.
Fixed it for ya.
