I will also note that when Germans in WWII destroyed their maps of minefields, and in the Falklands when Argentinian commanders destroyed their maps of minefields, prisoners were forced to probe and remove mines.
One way the Geneva Convention works is by reciprocity. If a party violates it, it removes a corresponding protection from the side that violates it.
In like manner, illegal combatants are not granted POW protection by the Geneva Conventions. Rather the US extends POW treatment as a courtesy, as an example, and as a means to gain intelligence information.
Well, the Germans in WW2 operated outside the bounds of civilized behavior, in my opinion. So did the Japanese. They deserved pretty much whatever they got, although civilians should have been protected as non-combatants.
I am not familiar with the Falklands situation at all.
I believe the Geneva Convention applies to
1) Forces of a recognized government
2) Forces of a Government which was a party to the Geneva convention
3) Soldiers captured in Uniform.
I don’t believe ANY of the above apply to Muslim terrorists and think they should be handled by military courts martial and hanged if found to be involved in piracy or terrorism,
