The impact of the War on Terror post-September 11, 2001, has been profound and multifaceted. Initiated by the U.S. response to terrorist attacks, it involved military action in Afghanistan aimed at dismantling al-Qaeda and toppling the Taliban regime. The war had significant implications, including heightened security measures domestically and internationally, leading to debates on civil liberties and human rights. The conflict also prompted changes in U.S. foreign policy and relationships with other nations, alongside generating prolonged military engagements. Additionally, the war has influenced global perceptions of terrorism and has seen an increase in recruitment and activism by extremist groups.
