You can do something: contact the ICC (International Criminal Court) in the Hague. Recognizing international law is crucial in the current period we're living in, and could prevent further catastrophes like the ones we saw during the 20th century with WWI and WWII, Stalinism, the rise of fascism, and numerous other examples that could have been avoided.
It's simple--we owe it to the children, and to ourselves. Want a more peaceful world? Contact the ICC now and complain about torture, the illegal invasions of Iraq and Afghanistan, and everywhere else the American State is meddling in. It takes a groundswell of global citizens to keep hammering-away on these things. It takes patience. Nothing happens overnight. Time's wasting.
Congress isn't going to do anything substantial before January 21st, 2009. This is irrelevant: there is no statute of limitations on war crimes. It's not just about Bush and Cheney, or even Rumsfeld. It's about tying-the-hands of future administrations from running amok across the globe against our wishes, and the wishes of the rest of the human race. You don't need Amnesty International or Moveon.org, or anyone else--take it to the Court.
