and Imam of Oman gathered their forces to expel the Saudis but were persuaded by the British Government to exercise restraint pending attempts to settle the dispute by arbitration. A British military build-up took place, leading to the implementation of a standstill agreement and the referral of the dispute to an international arbitration tribunal. In 1955 arbitration proceedings began in Geneva only to collapse when the British arbitrator, Sir Reader Bullard, objected to Saudi Arabian attempts to influence the tribunal and withdrew. A few weeks later, the Saudi party was forcibly ejected from Hamasa by the Trucial Oman Levies. The dispute was finally settled in 1974 by an agreement, known as the Treaty of Jeddah, between Sheikh Zayed (then President of the UAE) and King Faisal of Saudi Arabia.

Much deliberation took place in the British parliament, with a number of MPs arguing that the Royal Navy would not be able to defend the Trucial Sheikhdoms. Denis Healey, who, at the time, was the UK Secretary of State for Defence, reported that the British Armed Forces were severely overextended, and in some respects, dangerously under-equipped to defend the Sheikhdoms. On 16 January 1968, British Prime Minister Harold Wilson announced the decision to end the treaty relationships with the seven Trucial Sheikhdoms which had been, together with Bahrain and Qatar, under British protection. The British decision to withdraw was reaffirmed in March 1971 by Prime Minister Edward Heath. The region faced a
