Overlooking the charges of torture, Obote promotes Amin to major and to colonel and deputy commander of the army and air force. Shortly after independence Amin is sent to Israel on a training course. He will became a favourite of the Israelis when he acted as a conduit for the supply of arms and ammunition to Israeli-backed rebels fighting a war in southern Sudan. Following a financial scandal implicating Obote and Amin in gold smuggling, and on the back of growing opposition from King Mutesa, Obote suspended the constitution, arrested half his cabinet, and installed himself as president for life. King Mutesa driven from his palace in a military operation led by Amin and forced into exile. A new constitution abolishes all the country's kingdoms. Amin is subsequently promoted to major-general and appointed chief of the army and air force. He begins to build a support base in the army by recruiting from his own Kakwa tribe. However, his relations with Obote started to sour. An unsuccessful attempt is made to assassinate Obote. Okoya, the deputy chief of the army and Amin's sole rival among senior army officers, told Obote and Amin that the net is closing in on the perpetrators and that all will be revealed at a meeting which led to Okoya and his wife are shot dead at their home. Relations between Obote and Amin deteriorate further following the murder. In November Obote removes Amin from his command positions and places him in an administrative role. Amin discovered that Obote intended to arrest him on charges of misappropriating millions of dollars of funds. On 25 January, while Obote is out of the country attending the Commonwealth Conference in Singapore, Amin stages a coup that is later reported to have been backed by Israel and welcomed by the British. Amin's military government accuses Obote and his regime of corruption, economic mismanagement, suppressing democracy, and failing to maintain law and order. The coup is initially supported by Ugandans, with Amin promising to abolish Obote's secret police, free all political prisoners, introduce economic reforms, and quickly return the country to civilian rule. However, elections will never be held during Amin's reign.Amin is declared president and chief of the armed forces. Almost immediately he initiates mass executions of officers and troops he believes to be loyal to Obote. Determined to make Uganda "a black man's country", Amin expels the country's Indians and Pakistanis, reportedly after receiving a message from God in a dream. With the true nature of Amin's regime becoming apparent, the British and Israeli governments began to backpedal on their support, refusing to sell him more arms. Amin then looks to Libya for aid, promising the Libyan leader that he would turn Uganda into an Islamic state. The Soviet Union also provided aid and arms for a time. Amin then decided to challenge Britain and the United States, breaking relations with Israel, and throwing his support behind the Palestinian liberation movement. British property in Uganda is appropriated, business relations between the two countries are restricted, and those Britons remaining in Uganda are threatened with expulsion. To secure his regime Amin launches a campaign of persecution against rival tribes and Obote supporters. In some cases entire villages are wiped out. Cabinet ministers are informed that they will be subject to military discipline. Ruling by decree, Amin created his own security apparatus to identify and eliminate opponents. During 1975 he stages a publicity stunt for the world media, forcing white residents of Kampala to carry him on a throne then kneel before him and recite an oath of loyalty. In the summer, Denis Hills, a Uganda-based British subject, is sentenced to death by the regime for describing Amin as a "village tyrant." The sentence is dropped only after the British foreign secretary travels to Kampala to plead for Hills' life. Hills, who is eventually freed, later warns against viewing Amin as a buffoon or murderer, explaining that Amin's "aggressive black national leadership" had won him many admirers in Africa. Amin becomes personally involved in hostage negotiations with Israel when pro-Palestinian guerrillas hijack an Air France passenger jet carrying 105 Israelis and Jews on 27 June and order it fly to Entebbe in Uganda. However, he is deeply humiliated when Israeli commandos stage a successful raid and rescue the passengers on 1976 4th July. Only two of the hostages are killed during the 58-minute operation and only one is left behind; Dora Bloch, a British-Israeli grandmother who had been released by the hijackers for medical treatment. Causing the Israeli Prime Minister to accuse Amin of "collaborating with the terrorists while using deceit and false pretences" during the hostage negotiations. Accusing him also of allowing reinforcements to join the original four hijackers that were already on board. In the wake of the Entebbe raid a furious Amin has Dora Bloch and more than 200 senior officers and government officials executed. He also expelled foreigners from Uganda and unleashes a new round of violence, ordering the execution of anyone suspected of opposing him. At the end of July Britain breaks off diplomatic relations with Amin's regime. Amin declares that he has beaten the British and confers upon himself the title of 'Conqueror of the British Empire'. The US, meanwhile, cuts off aid to Uganda, with President Jimmy Carter saying that Amin's policies "disgusted the entire civilized world." In an attempt to divert attention from the country's internal problems in 1978, Amin launched an attack on Tanzania, a neighboring country to the south, at the end of October. Tanzanian troops, assisted by armed Ugandan exiles, quickly put Amin's army to flight and counter-invade. Eventually leading to the downfall of his regime and an official statement from the Ugandan Government stating that Amin was free to return but would have to "answer for his sins" and be dealt with according to the law. Although nothing in particular was done to prevent such event from happening the country was under test as the next leader Obete ruled the country similarly and was removed from his position by the people and government before things escalated quickly, in subject creating a democratic society with checks and balances were the only reasons why such a reign was prevented.
