The primary goal of suicide bombers striking in Israel is probably to kill Jews - terrorising the remaining populace is probably a secondary goal.
I also have an issue with the "by subnational groups or clandestine agents" label. Surely military personally are able to engage in terrorism as well. Then again, I might be misunderstanding what they mean by "subnationak groups or clandestine agents"
I have a problem with that label too, see the OP. Anyway, your first point is debatable to say the least.
