This was the story behind the amazing evolution of Fischher's friend Hans-Joachim Klein, the penitent terrorist.  Klein had joined the Revolutionary Cells in Germany and had united with Carlos the Jackal believing that he was going to put his mechanic's skills to good use in a left-wing military organization, fighting Nazism in its modern disguises.  The Revolutionary Cells sent him for miltary training in an Arab country. In his intereview on this theme with Cohn-Bendit in the mid nineteen-eighties, Klein did not specify which country, but wherever it was, the place did not agree with him.  He found himself in a military training ground where in one part of the camp,European leftists singing left-wing songs received their anti-Zionists military training and , in another part, European fascists singing fascist songs received their own anti-Zionist military training.

The Palestinian movement tturned out not to be an anti-fascist or anti-Nazi cause at all.  It turned out to be an anti-Jewish cause.  Klein was horrified.  His mother had been imprisoned for a while in Ravensbruck, the Nazi camp and died later on from her sufferings there, when he was still a little child.  In his adulthood, he began to imagine or perhaps to fantasize, that she was Jewish--a not uncommon fantasy among modern Germans.  That was why he abandoned the Revolutionary Cells and then went even further and accused his old comrades among the German guerrillas not just of having betrayed the revolutionary ideal but of being out-and-out anti-Semites.  That was a shocking accusation. Klein was disturbed by something else at the Palestinian military camp,too, and this was a cult of suicide--a weird phenomenon that he was among the first to notice, back in the seventies.
