in the Pact of Steel. Italian foreign policy went through two stages during the Fascist regime. Until 1934–35, Mussolini followed a "modest ... and responsible" course and following that date there was "ceaseless activity and aggression". "Prior to the Italian invasion of Ethiopia, Mussolini had made military agreements with the French and formed a coalition with the British and French to prevent German aggression in Europe." The Ethiopian War "exposed vulnerabilities and created opportunities that Mussolini seized to realise his imperial vision" Britain At the Nyon Conference of 1937, Italy and the United Kingdom "disclaimed any desire to modify or see modified the national sovereignty of any country in the Mediterranean area, and agreed to discourage any activities liable to impair mutual relations." Italian diplomatic and military moves did not reflect this agreement. In the aftermath of the Italian invasion of Abyssinia, British and Italian forces in North Africa were reinforced. Due to various Italian moves, in July 1937, the British decided "that Italy could not now be regarded as a reliable friend" and preparations began to bring "the defences of the Mediterranean and the Red Sea ports up-to-date". In 1938, a weak armoured division was established in Egypt and further army and air force reinforcements were dispatched from Britain. With rising tension in Europe, in June 1939, the United Kingdom established Middle East Command (MEC) in Cairo to provide centralised command for British army units in the Mediterranean and Middle East theatre. All three branches of the British military were made equally responsible for the defence of the area. The authority of MEC included Aden, British Somaliland, Cyprus, Egypt, Eritrea, Ethiopia, Kenya, Greece, Libya, Palestine, Iraq, Sudan, Tanganyika, Transjordan, Uganda and the shores of the Persian Gulf. If necessary, command would be exerted as far away as the Caucasus and the Indian Ocean. The purpose of the command was to be "the western bastion of defence of India", keep British supply lines open to India and the Far East, and keep the Middle Eastern oilfields out of Axis hands. Upon the establishment of MEC, it was ordered to co-ordinate with the French military in the Middle East and Africa as well as liaise with the Turkish General Staff and possibly the Greek General Staff. On 19 October 1939, the Treaty of Mutual Assistance was signed between the United Kingdom, France and Turkey and British military forces were authorised to
