TBF, I don't think Lawrence was supported at all well by the FO in relation to his dealings with the arabs. You pick that up in Seven Pillars and it runs like a thread through the whole book. I can honestly say that having been a child out there (Libya) for six years and dad having served out there, the west gets an entirely wrong view of the Arab. We really didn't do ourselves any favours.
The Arabs will sell anything to anyone, that includes Oil. Suez has been an Egyptian possession for donkeys now, trade still flows, our companies work in Saudi to the benefit of both parties, but we viewed the tribal differences as childish.
In later years dad worked for Oilfield contractors importing Cats and Oilfied gear and Land Rovers. Mum worked for the Department of Public works in Benghazi. Her boss was all over Europe, buying for his own business as well. Her Letters from him are quite a surprise and he wasn't slumming it. They bot dealt with Syrians, Lebanese, Jordanians in fact from all over and one of my childhood mates still lives in Tripoli (Lebanon) and also has a London address. They have a completely different outlook to the fundamentalists, with who they frankly wouldn't drink Shahi.
In later years as Customs I had occasion to seize books about nuclear fission going to Tripoli (Libya) that were basically textbooks for those studying physics at a London University because of the sanctions. The seizures were pointless because they could be obtained through other means.
The attitude of the west to the ME & arabs in general has long been a bug bear of mine. To not listen to specialists & experts in the area when forming strategy & aligning national interest coupled with an ethical approach is idiocy of the first degree. History keeps repeating itself in the ME & arab north africa thanks in no small part to the west not learning & paying attention.
Ref TEL, he & his comrades with Arab armies were stuck between the buffoons in the FO & the Indian Office & their conflicting interests/aims in the Arabian peninsula & Iraq/Jordan. The problems as reported by Gertrude Bell with how both organisations ran counter to each were staggering in their stupidity, none of which was helped by the duplicity of the French in Syria & Iraq in the end stage of the war & during the various peace conferences.
