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,
Geneva convention applies to combatants who keep the Geneva convention.
1. use a uniform recognizable at a distance
2. Have a chain of command
3. treat prisoners according to the Geneva convention.
4. Avoid damage to non-combatants and civil structures
Terrorists fail at least 2 of 4.
Since the Nazi SS didn’t follow Geneva Convention, they would not be protected.
When combatants hide behind women and children, or in schools or hospitals, the combatant does not thereby gain protection, they rather remove protection.
The rules were written that way to be sure that no combatant ever had any incentive to hide behind non-combatants.
