Hopefully this belongs here, it's a bit of a strange subject and doesn't fit neatly in either political or ethical forums.
Some of the discussion on the thread on the Yemeni Civil War has been about suicide bombing, and whether it is right to support forces who use suicide bombing as a tactic if it's against a foe who is much worse.(Such as Al Qaeda) Coming out of this line of thought, I think there are two questions which really can be asked:
1. Is suicide bombing necessarily a terrorist act, or does it have anything to do with whether the target is military or civilian, or on whether the enemy uses the same tactic?
2. If suicide bombing IS a terrorist act, can it be condoned under any set of circumstances?
Some of my thoughts:
There are some old arguments which claim that many things which would be considered terrorism in times of peace are more properly considered part and parcel to a larger struggle when you have a context like a civil war, or a foreign occupation. For example: Trotsky made the argument that terrorism was useless, but that if someone had managed to somehow assassinate or blow up General Franco and his chiefs of staff in the middle of the civil war, this would not be terrorism. Similarly we can consider the use of suicide bombing by Kurdish fighters against ISIL: Very few people will deny that the population of Rojava Kurdistan are currently fighting for their lives, and not just for some sectarian cause or another. Does the fact that they are likely to experience mass murder if they lose against ISIS something which excuses the use of suicide bombings, or is this a line that you just don't cross?
