India Needs a Stronger Response to Pakistani Buffer Zone Airspace Violations

India and Pakistan have long upheld a mutual agreement restricting military aircraft operations within a 10-kilometer buffer zone along their shared borders. This measure aims to reduce accidental escalations and maintain a baseline of trust between the two nations. However, recent years have witnessed multiple violations of this agreement, particularly by the Pakistan Air Force (PAF), raising concerns over regional stability.​

Repeated Violations Undermine Trust

Instances of PAF aircraft approaching or breaching the 10-kilometer buffer zone have become increasingly frequent. Such actions not only contravene the established agreement but also elevate the risk of unintended military confrontations. Notably, during the 2019 Balakot crisis, Indian Air Force (IAF) jets conducted airstrikes deep into Pakistani territory in response to a terrorist attack in Pulwama, highlighting the fragile nature of the buffer zone understanding.​

Historical precedents further underscore this pattern. In 1959, a PAF F-86 Sabre intercepted an IAF Canberra over Pakistani airspace. Similarly, in December 2008, the PAF claimed to have intercepted two IAF jets inside Pakistani territory, a claim India denied. Such incidents reflect a recurring disregard for the buffer zone, particularly by the PAF, which has exploited the agreement’s lack of enforcement mechanisms to test India’s resolve.​

India’s Measured Responses and Strategic Restraint

Despite these provocations, India has often responded with restraint, adhering to strict engagement protocols to avoid escalation. While caution is commendable, it should not compromise national security. The Indian Air Defence (AD) systems, especially the S-400, possess the capability to detect and neutralize threats well beyond the 10-kilometer buffer zone. Granting these systems operational autonomy could enhance India’s deterrence posture.​

Advocating for Proactive Measures

Engaging PAF jets within the 10-kilometer zone, even if they are in Pakistani airspace, is a proportionate response that avoids deeper strikes into Pakistani territory, thereby reducing the risk of full-scale conflict. Unlike offensive airstrikes, surface-to-air missile (SAM) engagements are defensive and can be calibrated to minimize escalation while asserting India’s right to protect its airspace.​

The PAF’s actions during Operation Swift Retort, including targeting Indian military installations and violating Indian airspace, justify a proactive Indian response. Pakistan’s own air defense systems, such as the Chinese HQ-9, are deployed near the Line of Control (LoC), indicating its willingness to engage Indian aircraft. India must match this posture to maintain deterrence parity.​

Conclusion

Modern air defence systems are capable of rapidly tracking and targeting hostile aircraft. If Indian forces are constrained by excessive caution, they risk allowing adversaries to exploit these protocols to their advantage. A strong and immediate response to any breach would send a clear message: the buffer zone agreement must be respected, and repeated violations will no longer be tolerated.
