What is the reason for the failure of Iran's oil nationalization movement?

Iran is a country rich in oil resources, located on the northern shore of the Persian Gulf. Its oil reserves reached 1.954/.995 million tons, but Anglo-Iranian oil company has the right to exploit oil. 1933 The British-Iranian oil agreement stipulates that the Iranian government can only get 20% profit. British-Iranian oil companies formed a "country within a country". It is under the jurisdiction of the British military and police, and Iranian law cannot be applied here. Iranian workers are exploited, but they have no right to strike. After World War II, American, British and Soviet troops successively withdrew from Iran, but Britain still enjoyed great rights and interests in Iran. American forces also vigorously infiltrated Iran in an attempt to replace Britain.

Where there is oppression, there is resistance. Venezuela achieved a 50-50 share of oil profits, Mexico nationalized oil in 1938, and Saudi Arabia and Aramco achieved a 50-50 share in the autumn of 1950. In this context, the Iranian oil nationalization movement broke out. 1950 In March, oil workers in Equestrian Port went on strike, and students and staff marched in unity. On April 22nd, King Pahlavi sent military police to suppress it. In Parliament, Mossad advocated nationalization, while Prime Minister Razmara opposed nationalization in his speech and was assassinated four days later. The Minister of Education was also assassinated. The king's power was weakened. 1951March 14, the Iranian national assembly passed the oil nationalization bill proposed by Mossad, the leader of the national democratic movement. On April 28th, Parliament elected Mossad as the new Prime Minister. On April 30th, the Iranian National Oil Company was established and the Anglo-Iranian Oil Company was nationalized. In order to counter Iran's oil nationalization law, the British government imposed an economic blockade on Iran, and the United States mediated and took the opportunity to control its oil. 1In August, 953, the United States and Britain successfully supported the coup of King Pahlavi. Mossad was arrested and imprisoned, and later died in prison. The vigorous anti-British nationalist movement was suppressed. Oil companies in western countries have formed an Iranian oil holding organization (IOP) to replace Anglo-Iranian oil companies, with Britain accounting for 40%, the United States accounting for 40%, Shell accounting for 14% and France accounting for 6%. 1954,10129 October, after arduous negotiations, the two sides recognized in principle that oil resources and facilities are owned by Iran and managed, operated, sold and exported by the United States and Britain.
