By her Treaty of Perpetual Alliance with Great Britain, signed in 1936, Egypt undertook to give to her Ally, in time of war and within the borders of her own territory, every facility and aid in her power. These obligations she has respected in letter and in spirit. As a result she finds herself today, while still a neutral, acting as host to large armies drawn from all the quarters of the globe. These troops are within her borders on her express or tacit invitation. To them—as allies and as allies of her ally—is extended the traditional hospitality of the land. At the same time their presence raises numerous problems. One of these is that of criminal jurisdiction. Egypt has only recently emerged victorious from a long struggle to free herself from restraints on her national sovereignty in judicial as well as in other fields.
