Psychologists attribute great significance to slips of the tongue. In such moments, the train of normal speech is interrupted by a word that seems to be out of context. Yet analysts say that this interruption actually betrays an inner truth hidden, consciously or not, behind the screen of “normal” speech. I suggest here that the 1931 Arab–Jewish transportation strike against the Mandatory government in Palestine can be seen as a historical slip of the tongue in the history of the Israeli–Palestinian conflict.
