If Israel is hell bent on keeping destroying their homes and replacing them with their own, stealing land, uprooting their olive tress with they make a living on, shooting at fishermen, shooting their kids for throwing stones or rocks, keeping them fenced in, jailed them without trials and abusing them while in their prisons, continuous threats of how all the land belongs to the Jews, then yes I do think they have a right to defend themselves,
and it was the Zionist who moved in like hoards, with full intent on ridding the land of their presence. I am never for violence but in this case they need to defend themselves.
I am only sorry that Gaza does not have a stronger military, and seem to be at the mercy of Israel and Israel's propaganda and state of the art weapons and as PM Bibi calls it their "fighting spirit". This is not the OT times.
