TRIANGULAR DETERRENCE BENEATH THE WAVES: INDIA’S NAVAL NUCLEARIZATION, PAKISTAN’S STRATEGIC RESPONSE, AND CHINA’S EXPANDING MARITIME INFLUENCE IN SOUTH ASIA

This article examines the strategic transformation of South Asia’s maritime security landscape driven by India’s pursuit of a credible sea-based nuclear deterrent. The operational deployment of SSBNs such as INS Arihant and the development of long-range SLBMs like the K-4 and K-6 signal India’s intent to project power across the Indian Ocean and secure second-strike capabilities. While these developments may enhance India’s deterrence posture, they pose complex challenges for Pakistan, which has traditionally relied on land-based deterrence and conventional military balance. Pakistan now faces the emergence of a concealed and survivable nuclear threat beneath its maritime borders, raising concerns over crisis instability, command and control vulnerabilities, and the risk of miscalculation. In response, Pakistan is adopting a multidimensional strategy that includes asymmetric deterrence, naval modernization, development of nuclear-capable cruise missiles, and active participation in regional diplomacy and multilateral forums. The article also highlights broader implications for global non-proliferation norms, environmental safety, and Indo-Pacific power dynamics. It concludes by emphasizing the need for strategic foresight, doctrinal clarity, and cooperative maritime governance to prevent escalation and preserve regional stability.
