By way of interpretation of the Geneva Conventions, Yeru is correct in that these terrorists or 'detainees' do not fall under any category made in the Conventions. But also keep in mind the conventions were drafted before terrorism became the preferred method of protest by the more extreme elements of humanity.
Putting aside the Geneva Convention concern, the US military are making a huge error in PR by not allowing the Red Cross access to these detainees. By taking that stance they fuel the conspiracy theories.
The International Red Cross (Red Cresent) Organization is an Independent Neutral Organization focussed on ensuring dignity and respect to all humans, combatants of all sides. These detainees fall under the mandate of the International Red Cross. The International media condemned Iraq for not allowing the Red Cross to have access to some of the coalition forces that were captured.
I supported the need to oust Saddam. I disagreed with the way the US approached the conflict (bypassing the UN), but support the military guys and gals who went over there to do the dirty work. I regret the loss of life of all parties, especially the innocents killed.
That said, I cannot understand why the US military would refuse access to the Red Cross. Any ideas on that one Yeru?
