rickortreat,
Hold on a second about "the Taliban."
The Taliban are essentially a political party. They were in control of a recognized government - Afghanistan. We attacked Afghanistan, and ousted the government (as a consequence of their shielding Al-Quaeda). They've adopted terrorist-style tactics since that time, meaning that, in my eyes, they have a choice to make:
1) Declare that they are the sovereign government of Afghanistan, and thereby admit that, due to their tactics, they are war criminals
2) Declare themselves an organization completely independent of the government, and are therefore, by definition, terrorists
Here's the problem: we seem to be bound by international law to treat them the same way regardless of what we choose. I think that that's wrong. I believe for them to have the protection of the Geneva Convention, they have to pick choice 1 above, or, in my opinion, terrorism should become the default form of combat in any engagement, and the Geneva Convention is obsolete. Let's face it - in terms of combat, a terroristic style is advantageous.
There's problem number 1 for your new world government model, Skander. Appropriately distinguish between terrorism and armed conflict, and provide an appropriate method for dealing with the former under new international law.
I'm serious about that challenge, by the way, if anyone wants to take it up. If a world government is ever going to succeed, these are the types of problems it has to effectively police. Personally, I don't think that anyone has currently come up with a good answer to terroristic-style attacks.
