England and Egypt 295 defence seems indeed to belong to ideas of imperialist strategy long out of date. So long as the British Empire commands sea and air and controls the Sudan, imperial communications are secure whether there are British troops in the Cairo citadel or no. The right to main- tain an air base in the Canal zone would, in the military sense, be far more valuable than the right to maintain battalions of infantry in Cairo.

We have, then, to examine the ques- tion as to how far such a guarantee is now necessary and how far such protection compensates for the preju- dices that it causes to the relations between the English and Egyptian peoples. We must note in the first place that all such rights have been abandoned both in form and in fact in respect of Constantinople and the Christians of Turkey, and that that city and those communities are of more international and of almost as much imperial importance as are Cairo and the foreign or Christian communities of Egypt.
