No, i'm asking you to define terrorism, tell me what it is.
Terrorism is the deliberate targeting of innocent civilians.
then wouldn't' that rule out Hammas as being terrorists in this instance, assuming we use your own criteria to terrorism which relates to 'innocent civilians'. If the guy wasn't' 'innocent' but had indeed aided the Israeli authorities, then his civilian status becomes suspect.
I'm not attempting to defend this barbaric act, what I'm trying to ascertain is what counts as terrorism.
