The 9/11 Attacks, 20 Years On
Two decades on, we reflect on the profound impact the 9/11 attacks had on security and global strategy.
The attacks by the Al-Qa’ida terrorist organisation on the World Trade Centre in New York and the Pentagon on 11 September 2001 were cataclysmic in their effect on the global strategic environment.
After two major wars and a dramatic evolution of the terrorist threat, we mark the 20-year anniversary of 9/11 through a series of events, published analysis and videos.
