My Theories and Conjecture on the Hamburg Cell
I think the four Hamburg Cell members were committed to their Jihad long before 1997, which is why Jarrah was able to change course and home town in Germany at the drop-of-a-hat that September. Prior to embarking on their Jihad Khalid Sheikh Mohammed and his nephew Ramzi Yousef both studied in Western countries, engineering in America and electronics in Britain respectively. I guess the Hamburg Cell members were doing the same – getting an education while looking for opportunities to advance their cause. That cause, their grievance, can be summed up in three words: American Foreign Policy. And, as confirmed by my conversation with Yousef, very specifically the USA's blind (self-harming) support for Israel. Yousef even lamented the 1995 murder of Israeli Prime Minister Yitzhak Rabin, calling it a lost last chance for peace.
