Operation Sindoor: How India's anti-terror doctrine shifted one year on
Synopsis
A year after India launched precision strikes on nine terror camps inside Pakistan and Pakistan-occupied Kashmir, a new analytical report argues Operation Sindoor did more than retaliate — it institutionalised a new deterrence doctrine under which nuclear blackmail no longer constrains India's military response to state-sponsored terrorism.

One year after Operation Sindoor, the Indian military campaign launched on 6–7 May 2025 continues to be assessed as a defining turning point in India's evolving security doctrine, signalling a fundamental shift in New Delhi's approach to terrorism and national security, according to a report published in the Sri Lankan Guardian.
Background: What Triggered Operation Sindoor
The immediate trigger was the 22 April 2025 terror attack in Pahalgam's Baisaran Valley in Jammu and Kashmir, carried out by The Resistance Front (TRF) — described in the report as a proxy outfit of the Pakistan-based terror group Lashkar-e-Taiba, allegedly backed by the Pakistan Army and Inter-Services Intelligence (ISI). The massacre killed 26 people, including 25 tourists and one local pony ride operator who reportedly tried to shield tourists from the attackers. Several victims were newly married; many were shot at close range in front of their families. Witnesses said the attackers singled out victims based on religion, forcing them to recite the Islamic kalima to identify non-Muslims.

Point of View
The prevailing assumption was that Pakistan's nuclear arsenal functioned as an effective ceiling on Indian military responses to sub-conventional provocations. If New Delhi has genuinely recalibrated that calculus, the strategic implications extend far beyond the subcontinent. Yet the report draws heavily on government-produced material, including a Defence Ministry documentary, and quotes analysts broadly sympathetic to India's position. Independent verification of casualty figures and the precise damage inflicted on Pakistani air defences remains limited. The doctrine may be new; the evidence base for its full success is still being assembled.
