The first anniversary of Operation Sindoor, launched on the night of May 6-7, 2025, in response to the Pahalgam terror attack that killed 26 civilians including 25 tourists, has prompted a comprehensive official stocktaking of India’s counter-terrorism doctrine, military capabilities, and diplomatic achievements. Prime Minister Narendra Modi’s tribute to the armed forces was accompanied by a joint press conference by senior military officials in Jaipur, where Lieutenant-General Rajiv Ghai, who served as Director-General of Military Operations during the operation, declared that “no terror sanctuary inside Pakistan remains safe anymore” and that the operation had “fundamentally altered the security landscape.”
However, the anniversary also brought into sharp focus several unresolved strategic questions that the Congress party, among others, raised publicly. The opposition specifically flagged the contrast between India’s diplomatic outreach after the operation and Pakistan’s continued international rehabilitation, including what it described as Pakistan Army Chief Field Marshal Asim Munir being “embraced with warmth” by U.S. President Trump and the revelation, attributed to Chief of Defence Staff General Anil Chauhan, that India had suffered “initial losses due to tactical errors” before adapting and carrying out precision strikes.

For UPSC aspirants, this topic is centrally important to India’s security policy, civil-military relations, nuclear deterrence theory, India-Pakistan relations, India-US relations, and the evolving doctrine of sub-conventional warfare. The anniversary assessments reveal both the genuine achievements of the operation and the strategic and communication challenges India must address to consolidate the gains from what was genuinely a watershed moment in Indian military history.
Background and Context: The Strategic Environment Before Operation Sindoor
Five Important Key Points
- The Pahalgam terror attack of April 22, 2025, which killed 26 civilians, was the deadliest terror strike in Kashmir since the 2001 Parliament attack and was traced to Pakistan-based terrorist infrastructure, providing India with clear casus belli for military action under the emerging doctrinal framework of targeted counter-terror strikes.
- Operation Sindoor, launched on May 7, 2025, was described by Air Marshal Awadhesh Kumar Bharti as destroying nine terrorist camps on May 7 and subsequently striking 11 Pakistani airfields, with the Indian Air Force claiming the destruction of 13 Pakistani aircraft including “one high-value airborne asset at a record distance of over 300 kilometres.”
- The ceasefire that halted Operation Sindoor on May 10, 2025, was first announced by then U.S. Secretary of State Marco Rubio, which the Congress party has repeatedly cited as evidence of U.S. intervention in determining the conflict’s conclusion, raising questions about India’s claimed strategic autonomy.
- India placed the Indus Waters Treaty in abeyance as a consequence of Pakistan’s continued sponsorship of terrorism, representing the first such suspension since the treaty was signed in 1960, though the Ministry of External Affairs confirmed on the anniversary that this position remains unchanged.
- Vice-Admiral A.N. Pramod’s anniversary statement that Operation Sindoor “exposed the limitations of Pakistan’s nuclear deterrence narrative” represents a significant doctrinal claim, suggesting India believes it successfully called Pakistan’s nuclear bluff by conducting conventional strikes without triggering nuclear escalation.
India’s Evolving Counter-Terror Doctrine: From Restraint to Calibrated Response
Operation Sindoor represents the culmination of a doctrinal evolution in India’s approach to cross-border terrorism that began with the surgical strikes of September 2016 and the Balakot airstrikes of February 2019. Each of these episodes pushed India’s response doctrine progressively further across the Line of Control and deeper into Pakistani territory, establishing what analysts have termed a doctrine of “calibrated escalation” — conventional military action designed to impose costs on Pakistan for sponsoring terrorism while remaining below the threshold of all-out war.
The Balakot strikes of 2019 were India’s first use of air power across the international boundary with Pakistan since the 1971 war, but they targeted a non-urban forested area and were accompanied by significant ambiguity about the extent of damage caused. Operation Sindoor, by contrast, involved coordinated Army, Air Force, and Navy action, targeted specific terrorist infrastructure as well as Pakistani military airfields, and resulted in acknowledged Pakistani aircraft losses. This represented a qualitative escalation in India’s willingness to impose military costs.
Lieutenant-General Ghai’s statement on the anniversary that “we have imbibed several lessons during Operation Sindoor and accordingly, changes are being made” suggests an institutional process of learning and adaptation that is consistent with professional military doctrinal development. His further statement that “the operation will remain in progress for as long as required” appears designed to sustain deterrence pressure on Pakistan.
Nuclear Deterrence and Pakistan’s Strategic Response
The most strategically significant claim from India’s anniversary assessments is Vice-Admiral Pramod’s assertion that Operation Sindoor “exposed the limitations of Pakistan’s nuclear deterrence narrative.” Pakistan’s nuclear doctrine has historically relied on the threat of first-use of tactical nuclear weapons to deter Indian conventional military action, a posture sometimes described as “full spectrum deterrence.” If India’s willingness to conduct sustained conventional strikes against Pakistani military targets without triggering nuclear escalation undermines the credibility of this deterrence posture, the strategic implications are substantial.
However, this claim requires careful analytical qualification. Pakistan’s nuclear threshold was almost certainly not reached during the limited duration and geographic scope of Operation Sindoor. The more important question — whether India’s actions have genuinely altered Pakistan’s calculus about the costs of sponsoring terrorism, or whether Pakistan will simply reconstitute its terrorist infrastructure and recalibrate its tactics — remains unanswered one year later.
The Diplomatic Deficit: Pakistan’s International Rehabilitation
The Congress party’s observations about Pakistan’s international rehabilitation deserve serious analytical consideration regardless of their political motivation. The specific claim that U.S. President Trump has been warm toward Pakistan’s Army Chief Field Marshal Asim Munir reflects a broader pattern in US-Pakistan relations where the United States has historically prioritised strategic considerations — access to Pakistani territory, intelligence cooperation, and Pakistan’s role as an interlocutor with Afghanistan — over holding Pakistan accountable for terrorism sponsorship.
India’s own diplomatic record after the Pahalgam attack and Operation Sindoor has been mixed. India secured expressions of solidarity from key partners including the United States, France, Israel, and several Gulf states in the immediate aftermath of the attack. However, the contrast between India’s post-Mumbai 2008 international isolation of Pakistan and Pakistan’s current international standing suggests that the diplomatic gains from Operation Sindoor have been more limited than the military achievements.
The ceasefire announcement coming first from the U.S. Secretary of State raises legitimate questions about the extent to which India controlled the narrative and timeline of the operation’s conclusion. A country that claims strategic autonomy and presents itself as a global power must be able to conclude major military operations on its own terms and timeline, or at minimum present its own account of why restraint was exercised without appearing to have yielded to external pressure.
Way Forward
India needs a comprehensive and proactive counter-terrorism diplomatic strategy that complements its military doctrine. This means building sustained international coalitions to hold Pakistan accountable at the Financial Action Task Force, the UN Security Council, and through bilateral diplomatic pressure on major powers that maintain warm relations with Islamabad.
India must also invest in strategic communication capacity. The inability to definitively counter U.S. claims of ceasefire brokerage — or to transparently address the CDS’s acknowledgement of initial tactical losses — creates information vacuums that adversaries and domestic critics can exploit.
The Indus Waters Treaty suspension should be converted from a diplomatic signal into a leverage mechanism with specific, publicly stated conditions under which India would be willing to resume treaty compliance, giving Pakistan concrete incentives for behavioural change.
