9/11

Explanation

“9/11” refers to the coordinated terrorist attacks on September 11, 2001, when al-Qaeda operatives hijacked planes and struck targets in New York City and Washington, D.C. The event killed nearly 3,000 people and triggered sweeping changes in security and policing. Governments expanded surveillance powers, strengthened border controls, and adopted counterterrorism laws with far-reaching implications for civil liberties. Critics argue that the post-9/11 security state has fueled racial profiling, Islamophobia, and the erosion of democratic accountability.
