If sending a bomb attached donkey to marketplace is not targetting civillians on purpose, I don't know what it is then. Irgun targeted civilians on purpose. There is nothing to discuss about it.
Your examples are irrelavent to the subject. Irgun was a terrorist organization. One must be either a stupid or a jew to deny that.
You don't know what a terrorist organization is then. I'll give you an example:
Strapping a bomb to a kid promising him eternal glory and heaven in order to kill a bunch of teens in a night club is a terror attack. Stabbing a 3 month old infant with a butcher knife and the entire family is a terror attack.
Something the Arabs and Islamists specialize in.
Everything the Irgun did was in retaliation, a response, for the thousands murdered by the Arabs for no other reason than because they were Jews.
