Operation Sindoor marked a new phase in India's counter-terrorism strategy, demonstrating that no terrorist site across the Line of Control (LoC) is beyond reach. Experts Harsh V. Pant and Sameer P. highlighted that the operation set a precedent for sustained deterrence and was India's first large-scale multi-domain military operation in South Asia. The operation targeted terror facilities in Pakistan and received support from countries including France, Israel, and Armenia, which endorsed India's right to self-defense. However, Western capitals largely responded with calls for de-escalation, reflecting shifting global priorities. During the operation, China openly supported Pakistan, deploying weapons and advocating for dialogue and investigations into the Pahalgam terror attack. Indian Army officials revealed a nexus involving Pakistan, China, and Turkey coordinating against India, including a disinformation campaign aimed at undermining India's position post-operation. Additionally, China has reportedly reshaped its Myanmar policy to exert pressure on India's northeastern region through security, economic, and proxy networks. These developments underscore a complex regional dynamic following Operation Sindoor, with India redefining its doctrine from restraint to retaliation in counter-terrorism efforts.
