Ziomatrix, why so many italics?
Eisenhower did say that his biggest political mistake was not supporting Britain over Suez.
If he had left well alone (as the US did over the Falklands), I foresee a good Suez Canal Zone acting to stop head-butting between Israel and Egypt. As Israel held the Sinai by the end of the Suez crisis, it might just hold onto it.
Nasser would fall due to having demonstrated incompetence. Whether the Aswan High Dam is built is uncertain.
Frankly, having shown resolution over Suez, Britain might retain an interest in the Gulf and expand its oil exploration there. You can expect Suez and Aden being too important for even that crackbrained idiot Harold Wilson to get rid of. Just maybe, the Ba'athist regime might fail to seize Iraq and Al-Fatah get an even bloodier nose in Jordan.
