why did they attack on 9/11

The attacks on September 11, 2001, were carried out by 19 hijackers affiliated with the Islamist militant organization al-Qaeda, led by Osama bin Laden. The motivations behind the attacks included retaliation for various US policies and actions perceived as hostile to Muslims: US support for Israel, American military presence in Saudi Arabia and the Middle East, sanctions against Iraq, and US involvement in conflicts affecting Muslims like Somalia, Chechnya, and Kashmir. Bin Laden viewed the attacks as a form of punishment against American "economic and military power" and aimed to deter America's influence in the Muslim world. Additionally, he framed the attacks as retaliation for past perceived injustices suffered by Muslims, including the destruction of high- rise buildings during the Israeli invasion of Lebanon in 1982, which inspired the targeting of the World Trade Center towers. The attacks were thus not random but rooted in a complex mix of political, religious, and ideological motives involving opposition to US foreign policies and support for Israeli actions against Palestinians, combined with a desire to provoke a larger conflict with the US to spark wider support for al-Qaeda's goals.
