There is a very strong argument that USA's involvement in the Middle East since the 1950s (1953 overthrow of democratically elected leader of Iran Mossadeq by CIA), 1980s, including the Iraq wars of 1990 and 2003 have inspired extremists opposing USA.
It was also widely speculated that USA surreptitiously encouraged Iraqi invasion of Kuwait in order to trap Iraq into confrontation. Iraq would not have invaded Kuwait if it understood it would be attacked by USA.

Quote:The 1953 Iranian coup d'état, known in Iran as the 28 Mordad coup, was the overthrow of the democratically elected Prime Minister of Iran Mohammad Mosaddegh on 19 August 1953, masterminded by the United States (under the name TPAJAX Project) and backed by the United Kingdom (under the name "Operation Boot").[3][4][5][6]
Mossadegh had sought to audit the documents of the Anglo-Iranian Oil Company (AIOC), a British corporation (now part of BP) and to limit the company's control over Iranian petroleum reserves. Upon the refusal of the AIOC to co-operate with the Iranian government, the parliament (Majlis) voted to nationalize Iran's oil industry and to expel foreign corporate representatives from the country.[7][8][9] Following the coup in 1953, a military government under General Fazlollah Zahedi was formed which allowed Mohammad-Rezā Shāh Pahlavi, the Shah of Iran (Persian for an Iranian king),[9][page needed] to effectively rule the country as an absolute monarch. He relied heavily on United States support to hold on to power until his own overthrow in February 1979.[7][8][9][10] In August 2013, 60 years after, the American Central Intelligence Agency (CIA) admitted that it was in charge of both the planning and the execution of the coup, including the bribing of Iranian politicians, security and army high-ranking officials, as well as pro-coup propaganda.[11][12] The CIA is quoted acknowledging the coup was carried out "under CIA direction" and "as an act of U.S. foreign policy, conceived and approved at the highest levels of government."[13]
Iran's oil had been discovered and later controlled by the British-owned AIOC.[14] Popular discontent with the AIOC began in the late 1940s: a large segment of Iran's public and a number of politicians saw the company as exploitative and a central tool of continued British imperialism in Iran.[7][15] Despite Mosaddegh's popular support, the AIOC was unwilling to allow Iranian authorities to audit the company accounts or to renegotiate the terms of its access to Iranian petroleum. In 1951, Iran's petroleum industry was nationalized with near-unanimous support of the Majlis in a bill introduced by Mossadegh who led the Iranian nationalist party, the National Front. In response, Britain instigated a worldwide boycott of Iranian oil to pressure Iran economically.[16] Initially, Britain mobilized its military to seize control of the British-built Abadan oil refinery, then the world's largest, but Prime Minister Clement Attlee opted instead to tighten the economic boycott[17] while using Iranian agents to undermine Mosaddegh's government.[18] With a change to more conservative governments in both Britain and the United States, Winston Churchill and the Eisenhower administration decided to overthrow Iran's government, though the predecessor Truman administration had opposed a coup.[19] Classified documents show that British intelligence officials played a pivotal role in initiating and planning the coup, and that the AIOC contributed $25,000 towards the expense of bribing officials.[20]
