Egypt agreed to respect freedom of navigation through the canal and it was agreed that British troops could return if the Suez Canal was threatened by outside power. Together, she and her accomplices secretly planned a two-stage invasion of Egypt, including cover-up. Israel would first attack Egypt in Sinai, then Britain and France would invade under the pretext of “separating the fighters” and protecting the canal, under the terms of the Anglo-Egyptian agreement of 1954, to withdraw all British forces from Egypt. One of the most laborious aspects has been the formulation of a plan on which both Britain and Israel have reached an agreement. The Israelis were suspicious of the British, but since the French did not agree to act without their British allies, they were forced to manage them.
