Phase IFoundation

Background

Overview

The GWOT profoundly reshaped international security, regional power balances, and the nature of conflict. Its legacy continues to influence counter-terrorism strategies, humanitarian crises, and the foreign policies of major powers, including India's engagement in West Asia and Africa.

The Global War on Terror (GWOT), launched by the United States after the September 11, 2001 attacks, was a comprehensive military, political, and ideological campaign aimed at combating international terrorism. Initially targeting al-Qaeda and the Taliban, it evolved into broader regime-change interventions with profound and often unintended geopolitical consequences.
