BackgroundCore Concept

Background

The September 11, 2001 attacks, carried out by al-Qaeda using four hijacked civilian aircraft, killed 2,977 people and destroyed the World Trade Center. The attacks proved that non-state actors operating from distant sanctuaries could inflict strategic shock on the world's most powerful military state. Before 9/11, terrorism was largely treated as a domestic law-enforcement problem. After it, terrorism became the organising principle of international security policy for two decades.

The international response was swift. The UN Security Council adopted Resolution 1373, imposing binding obligations on all member states: criminalise terrorism financing, tighten border controls, deny safe haven to terrorists, and share intelligence. Resolution 1373 also established the UN Counter-Terrorism Committee (CTC) as the primary multilateral oversight body. The Financial Action Task Force (FATF) was tasked with tracking illicit financial flows sustaining terror networks, including hawala transfers, state sponsorship, and drug-trafficking proceeds. Despite this institutional expansion, a foundational gap persists: the absence of a universally agreed definition of terrorism has blocked India's proposed Comprehensive Convention on International Terrorism (CCIT), pending at the UN since 1996.

The roots of the current South Asian security landscape stretch back to the 1979–89 US-USSR proxy war in Afghanistan. Arab volunteers were mobilised through ideological networks, and Pakistan served as the frontline logistics base. Leaders of Pakistani militant groups who participated in that conflict later founded Lashkar-e-Taiba (LeT) and Jaish-e-Mohammad (JeM). Al-Qaeda itself was secretly founded in Peshawar around May 1988, even before Soviet troops withdrew. The proxy war's end left the Af-Pak region deeply destabilised, with armed networks, weapons, and an entrenched jihadist ideology that had no post-war demobilisation plan.

The Topic Explained

The US Congress passed the 2001 Authorisation for the Use of Military Force (AUMF) immediately after the attacks. This broad legislative mandate has remained in force ever since, and every US president from 2001 onward has used it to justify military action in multiple countries without requiring fresh congressional approval for each new conflict. The AUMF effectively created a permanent legal basis for war, which critics argue bypassed democratic accountability.

The US-led Global War on Terror (GWOT) became the organising framework of American national security. Its most consequential extension was the 2003 invasion of Iraq, launched without UN Security Council authorisation, making it one of the most legally contested military actions of the post-Cold War era. The invasion dismantled Iraqi state institutions, including the army and civil bureaucracy, creating a prolonged power vacuum. At peak deployment, over 1,70,000 US troops were present. …
