Simply as a wild idea what if on Egyptian independence in 1922 the British negotiated a deal so that they received a canal zone similar to the one the US had in Panama on a 99 year lease rather than the 20 year deal they made in 1936? The zone is five miles either side of the canal with its own police, courts and judges, and Egytians are allowed to cross over from one side to the via the bridges freely except in military emergencies. Would this have any effect on a future Suez Crisis? If the British keep a permanent military presence in the zone as they did in our timeline and decide not to compromise like they did in 1954 will we see an earlier crisis? If it doesn't clash with the Hungarian revolution and the British have a similar treaty to their own in Panama might the Eisenhower and the US be more neutral than strongly against it?
