The difference is indeed the warnings given prior to detonation. As I've said they weren't always enough but if deliberately killing as many civilians is your goal why in HELL give a warning 3 hour prior?

Again i stress, the killing of civilians, deliberate or not is not the element that differentiates a terrorist from an Army.

A. British troops are on British territory as much as them being in India was British territory.

B. The Army's excuse was to protect Catholic civilians, initially this was true, and Catholics welcomed them, made them food, tea, homed them. Then the B Specials influenced them, Catholic support waned a bit, then Bloody Sunday flipped everything up. It was that moment that they stopped getting welcomes in Catholic Estates.

And Policemen are combat targets if they kill & act in combatant ways, as thew RUC frequently done. If they collude with Loyalists, as they frequently done, if they discriminate, as they frequently done.

This situation was complex and dirty on all sides & not ONE side has blood free hands. You would do well to try & understand that.
