Why it matters
Understanding the long-term legacy of 9/11 is crucial for analyzing current geopolitical tensions, privacy debates, and the evolution of modern counter-terrorism strategies.
Twenty-five years ago America saw the darkest chapter in its history and the world hasn't been the same since.On September 11, 2001, 19 al-Qaeda hijackers seized four commercial aircraft and turned them into weapons. Two planes crashed into New York's World Trade Center, one struck the Pentagon and a fourth crashed into a field in Pennsylvania after passengers fought back. The attacks killed 2,977 people from 90 countries and changed the course of American foreign policy and global politics.The US invaded Afghanistan weeks later and Iraq less than two years after that. But the legacy of 9/11 reached far beyond those wars. Governments expanded surveillance and border controls. Airports became more heavily securitised. Intelligence agencies changed how they shared information. Drones transformed warfare, while the internet transformed terrorist recruitment. Islamophobia and debates over immigration intensified.
