1. The Genesis of the 9/11 Attacks: Understanding the Roots
The September 11 attacks were not a spontaneous act of violence but rather the culmination of years of planning, ideological radicalization, and geopolitical tensions. To truly understand why 9/11 happened, it is essential to delve into the complex web of factors that contributed to this horrific event.
1.1. The Rise of Al-Qaeda and Osama Bin Laden
The emergence of al-Qaeda, led by Osama bin Laden, was a pivotal factor in the lead-up to 9/11. Al-Qaeda was founded in the late 1980s during the Soviet-Afghan War, initially to support the Mujahideen fighters against the Soviet Union. After the Soviet withdrawal, al-Qaeda shifted its focus towards targeting the United States, which it viewed as a primary obstacle to its goal of establishing a global Islamic caliphate.
Bin Laden’s personal grievances against the United States stemmed from several factors, including the presence of US troops in Saudi Arabia (home to Islam’s holiest sites) during the Gulf War, US support for Israel, and US foreign policy in the Middle East, which he perceived as biased against Muslims.
1.2. Al-Qaeda’s Ideology and Objectives
Al-Qaeda’s ideology was rooted in a radical interpretation of Islam that called for the overthrow of secular governments in Muslim countries and the expulsion of Western influence from the region. The group’s objectives included:
- Ending US support for Israel
- Removing US military presence from the Middle East
- Overthrowing secular regimes in Muslim countries
- Establishing a global Islamic caliphate based on strict Sharia law
1.3. Historical Grievances and Geopolitical Context
The 9/11 attacks were also influenced by a broader historical context of grievances and geopolitical tensions in the Middle East. These included:
- The legacy of colonialism and Western interference in the region
- The Israeli-Palestinian conflict
- The rise of Islamic fundamentalism
- The perceived hypocrisy of US foreign policy
2. Planning and Execution: How Al-Qaeda Orchestrated the Attacks
The 9/11 attacks were the result of meticulous planning and coordination by al-Qaeda operatives. The group spent years identifying vulnerabilities in US security and developing a sophisticated strategy to carry out the attacks.
2.1. Identifying Targets and Exploiting Security Weaknesses
Al-Qaeda operatives carefully selected targets that would have both symbolic and strategic value. The World Trade Center in New York City, as a symbol of American capitalism and economic power, and the Pentagon in Washington, DC, as the headquarters of the US military, were prime targets.
The hijackers exploited several security weaknesses in the US aviation system, including:
- Lax security screening procedures at airports
- The lack of reinforced cockpit doors on commercial airliners
- The element of surprise
2.2. Training and Preparation of the Hijackers
The 19 hijackers were carefully selected and underwent extensive training in al-Qaeda camps in Afghanistan. They were trained in:
- Basic flight skills
- Combat techniques
- Operational security
- Suicide tactics
The hijackers were divided into four teams, each led by a trained pilot. They entered the United States legally, using visas obtained through various means.
2.3. The Day of the Attacks: A Timeline of Events
On the morning of September 11, 2001, the hijackers boarded four commercial airliners bound for California. Within a short period, they overpowered the flight crews and took control of the aircraft.

3.1. Religious Justification: A Radical Interpretation of Islam
