Context
Background
& Causes

Tensions between the U.S. and extremist groups had been building for over a decade before 9/11.

🌍
U.S. Foreign Policy
Military presence in Saudi Arabia and U.S. support for Israel angered extremist groups in the Middle East.
☪️
Rise of Al-Qaeda
Osama bin Laden founded Al-Qaeda in the late 1980s and declared jihad against the United States.
🛢️
The Gulf War (1991)
U.S. troops stationed in Saudi Arabia — considered holy land — intensified anti-American sentiment.
📋
Years of Covert Planning
Hijackers trained at U.S. flight schools over several years, largely undetected by intelligence agencies.
⚠️
Intelligence Failures
The FBI and CIA failed to communicate key information that could have prevented the attacks.
