The article "9/11: Two Decades Later" from BBC's HistoryExtra is a reflection on the lasting impacts of the September 11 attacks. It explores whether 9/11 genuinely altered the course of global history, shaping U.S. foreign policy, the "war on terror," and global security. Despite its undeniable effect on U.S. politics, the article questions whether 9/11 was a defining moment in the broader context of geopolitical changes, particularly in relation to China and the Middle East.
