KV 5/34
Contradicting apologists who were attributing the terror to the desperate plight of Jews in Europe, the Irgun clarified that its attacks “were not acts of despair and not acts of revenge”, but calculated campaigns of terror, “acts of persons who believe that the Jewish Kingdom will be created by force”. Jews who believed otherwise were “Jews of the Ghetto, who are weak and faint-hearted and not strong enough for this revolutionary period."
This is typical of the Irgun's (and indeed the Hagana's and Lehi's) attitude throughout the Mandate period.
