About Operation Sindoor

• It was a military operation launched by India on 7 May 2025 in response to the Pahalgam terror attack of 22 April 2025, in which 26 civilians were killed.

Shift from “Dossier Approach” to “Zero Tolerance”

• End of the Dossier Era: Earlier, India largely relied on presenting evidence and diplomatic dossiers to the international community after terror attacks.
• Adoption of Zero Tolerance Policy: After the 2025 Pahalgam attack, India signalled a more proactive doctrine by treating cross-border terrorism as an “Act of War”.
• Shift towards Direct Deterrence: The approach marked a transition from reactive diplomacy to calibrated military and strategic response.
• Breaking the Nuclear Deterrence Barrier: India indicated that Pakistan’s nuclear posture would no longer prevent conventional counter-terror operations.
  • The policy aimed to establish stronger deterrence by conveying readiness to bear escalation risks to counter terrorism effectively.

Execution of Operation Sindoor

• Precision Strike Operation: Operation Sindoor was launched targeting nine identified terrorist infrastructure sites in Pakistan and PoK.
• Demonstration of Surgical Capability: Indian forces successfully neutralised the targets with precision despite heightened Pakistani preparedness.
• Effective Use of Air Power: The operation highlighted India’s advanced precision-strike and deep-target engagement capabilities.
• Tri-Services Coordination: The Army, Navy, and Air Force displayed strong operational synergy and integrated planning.
• Lessons from Kargil Applied: Unlike coordination gaps witnessed during the Kargil conflict, the operation reflected improved jointness among the armed forces.
• Validation of Theatre Command Concept: The success reinforced the rationale for integrated Theatre Commands with unified operational control across services.

Defensive and Retaliatory Success of Operation Sindoor

• Effective Missile Defence: India’s S-400 air defence system and indigenous “Kavach” systems intercepted most incoming Pakistani missiles during retaliatory attacks.
• Demonstration of Air Defence Capability: The operation showcased India’s growing multi-layered missile defence preparedness and technological capability.
• Precision Retaliatory Strikes: India responded with precision strikes using BrahMos and other missiles against key Pakistani airbases such as Nur Khan and Sargodha.
• Deep Strike Capability: The attacks demonstrated India’s ability to accurately engage strategic targets deep inside enemy territory.
• Controlled Escalation Strategy: A ceasefire was reached within 88 hours after India had achieved its primary military objectives.
• Strategic Restraint: India balanced decisive retaliation with calibrated restraint, avoiding prolonged escalation while signalling credible deterrence.

Way Forward

• Strengthening Defence Preparedness against China: India must accelerate military modernisation, advanced capability development, and long-term strategic deterrence to address the challenge posed by China.
• Promoting Atmanirbhar Bharat and Whole of Nation Approach in Defence: Greater focus on indigenous defence manufacturing, innovation, and advanced R&D in areas like drones, AI, missile systems, and electronic warfare is essential.
• Enhancing Public–Private Collaboration: DRDO and defence PSUs should deepen collaboration with private firms like Larsen & Toubro and Mahindra Group to strengthen innovation and self-reliance in defence production.
