For all who are interested, here is some information on the first two terrorist groups to operate in the Middle East (during the 1930s and 1940s):

From the first article, a quote from the Zionist newspaper of the time "The Front", August 1943:

Neither Jewish morality nor Jewish tradition can negate the use of terror as a means of battle.
...
We are quite far from moral hesitations on the national battlefield. We see before us the command of the Torah, the most moral teaching in the world: Obliterate - until destruction. We are particularly far from this sort of hesitation in regard to an enemy whose moral perversion is admitted by all.
But primarily terror is part of our political battle under present conditions and its role is large and great.

• It demonstrates, in clear language, to those who listen throughout the world and to our despondent brothers outside the gates of this country of our battle against the true terrorist who hides behind his piles of papers and the laws he has legislated.
• It is not directed against people, it is directed against representatives. Therefore it is effective.
• If it also shakes the Yishuv from their complacency, good and well.

Only so will the battle for liberation begin.

It appears that history is not without a sense of irony.
