Saudi Arabia's main concern was with North and South Yemen. Two Saudi brigades with supporting arms and aircraft remained in the north-west, the remaining four brigades with strong air support, and patrol units from the Frontier Force, were in the south-west. Saudi naval corvettes and patrol boats were on station in both the Red Sea and the Gulf.
Iraq's army of some twelve divisions was broadly divided between a force on the new frontier with Iran, a grouping facing Syria, and a central reserve, with the Iraqi Air Force's 350 combat aircraft supporting the army deployment and the navy's missile and patrol vessels at readiness in the waterways and the Gulf.
Iran, like Iraq, had largely made good the losses already sustained in the war between them. The bulk of the Iranian Army's ten divisions, half of which were armoured, were divided between the north-east sector facing Afghanistan and the western front, with strong reserves held centrally and in the main oil-producing areas of the south-west. The Iranian Navy patrolled the Gulf, and the 200 or so combat aircraft supported both army and naval deployment.
Syria's forces — none of which were by this time deployed in Lebanon (where UN peacekeeping forces backed up the small army) — were located with two armoured divisions each in the northern and eastern commands, while the two mechanized divisions remained near Damascus. Syria's strong air force and air defence command, which included 450 Migs, was deployed to challenge attack from any quarter.
Jordan's four divisions, all armoured or mechanized, were concentrated in the northern and eastern sectors, supported by nearly 100 F-5s, with a small naval force at Aqaba. Oman's relatively small, but efficient force of some 15,000 were deployed both to resist any further incursions from South Yemen and to guard the sea approaches. The two Yemens had armed forces of roughly similar size, the South primarily equipped with Soviet arms, the North with a mixture from the USSR and the West. Each had armoured and infantry brigades, MiG fighters and patrol craft. Both could threaten Saudi Arabia. Aden was virtually a Soviet naval base.
Thus were the various forces disposed when peacemaking in the Middle East was brought to a temporary halt. It was plain that when the two principal guarantors of the 1985 peace agreement were themselves at war — war moreover brought about by events far removed from the Middle East scene — the principal strategic aims of the Arab countries, with the exception of Syria and the inevitable dissension of South Yemen, were twofold. The first was to preserve the integrity and security of their own countries; the second, to preserve the political and military conditions that would enable them to resume implementation of the peace settlement as soon as possible. It seemed therefore to Saudi Arabia and Egypt, together with their supporters — Jordan, Iraq, Oman, the other Gulf states, Libya and Sudan — that their policy must be to isolate Israel and keep it in check; to prevent any interference by North or South Yemen; to support Iran both in maintaining its internal security and against Soviet incursions from Azerbaijan and Soviet-inspired activity in Baluchistan; and with the assistance of the United States and NATO to maintain or re-establish control of the eastern Mediterranean, the Red Sea and the Gulf.
It is not intended to give detailed accounts of how these objects were achieved. Indeed in the event there was, with two major exceptions, very little war prosecuted in the Middle East or South-West Asia during the few weeks of the Third World War. What fighting there was took place largely in Europe, and at sea and in the air. Enough to say here that the prospect of hostile action by Iraq, Syria, Jordan and Egypt, together with explicit United States warnings, kept Israel in check. Syria disallowed any Soviet proposals to fly in reinforcements, and was more conscious than ever of the proximity of Turkey, which together with the rest of NATO was by this time at war with the Soviet Union and had closed the Bosporus with mines, submarines, land-based weapons and other means. The first aim of joint Arab policy was achieved without bloodshed.
The second aim did involve some bloodshed. North Yemen, under intense pressure from most Arab nations, agreed to accept a joint Egyptian-Saudi Arabian force to assist North Yemeni troops in suppressing once and for all the Soviet-armed guerrillas infiltrating from South Yemen. Sanaa, Taiz and Ibb were all successfully cleared, and effective anti-incursion forces were established along the frontier between North and South Yemen.
