I barely know where to begin, what to include, what to leave out... 1962 maybe good. That marked the beginning of the Saudi backed Wahhabi Muslim World League. Perhaps the precursor in 1957 is better, when Britain and France endured their Suez crisis. Backing religious extremists against nationalists like Nasser or the Socialists in Yemen could have seemed acceptable to the oil company bosses and Intelligence agencies. Or we could start at the Battle of Sabilla in 1929 Arabia. That's when the Sauds used British armour, machineguns & planes to decimate the Ikhwan, a murderous band of religious extremists. To make lasting peace the Sauds allowed the Ikhwan who survived to form the new Saudi National Guard. The grandson of a survivor of the battle served in the National Guard before reviving Al Ikhwan in opposition to corruption in the kingdom. He led the Grand Mosque Seizure in 1979, where two of Osama bin Laden’s brothers were said to be present, but not Osama. Or just focus on Sayyaf and KSM? I'm going to sleep on it; it's tiring doing everyone elses job - I am a witness, not police, investigator or journalist. I'm a dyslexic mechanic. Thanks to anyone still reading this far.
