Maybe you can, then, clarify what the Geneva Conventions are supposed to be.
As far as my reading of them goes, it seems to me they are an agreement amongst signatory nations regarding the rights and privileges of prisoners of war and civilians, between belligerent nations at war with each other. So that, if we go to war with Germany, who is a signatory, we both must comply (because if we *don't*, then all bets are off regarding to how OUR prisoners will be treated). However, if we go to war with *Japan*, they didn't sign the treaty, and they're not bound by it - AND *neither* are *we*. This is how I understand it. It's a treaty signed among nations that they have agreed to honor even during war.
Now we have a situation where we're capturing enemy combatants who are not soldiers of a foreign government. The best that can be said of them is that they are criminals. But they also work under the umbrella of an extra-national organization which HAS declared war on us - and they also have not signed the Geneva Convention, nor have they made the slightest effort to abide by them, or to respect the Red Cross (or Crescent).
So, *we're* bound by the Geneva Convention - a treaty we signed - but THEY *don't* (because, they're not even a nation).
I think the precedent we should take, is the actions we took in the past against *piracy*. Many pirates were working for foreign governments, back in the days, but flew under the skull and bones, and not under any flag. I think we need a new set of international laws, because quite honestly, the present ones won't do for dealing with organizations such as al-Qaeda, which aren't going to be signing on. They're not a nation, and therefore, they have no civilians, they have no land, they can't be blockaded or economically sanctioned. They have no agreements with any other nation, and no pressure can be put on them. BUT they possess the money and resources that a nation can have. (Something that strongly suggests to me - they ARE receiving help from foreign governments).
We need a new set of rules. The old catch and release pattern of the Geneva Convention is useless against an army of fanatical, deadly martyrs.
