SHIFTING LINES OF DETERRENCE: THE 2025 INDIA–PAKISTAN CLASH AND THE RISE OF POST-BALANCE REALISM

Abstract

The India–Pakistan military escalation of May 2025, though brief, reshaped South Asia’s strategic landscape. This study asks: How did Pakistan, despite its smaller conventional capacity, achieve strategic and political advantage over India within a nuclearized balance of power system? Traditionally, the balance of power theory posits that parity deters unilateral dominance and ensures stability. Yet, the 2025 confrontation challenges this logic, as Pakistan secured a greater share of its operational and diplomatic objectives. Drawing on defense reports, think-tank analyses, and open-source intelligence, this paper argues that strategic clarity, adaptive doctrine, and credible signaling compensated for material asymmetry. To explain this deviation, the paper introduces post-balance realism—a refinement of classical and structural realism that incorporates technological adaptation, narrative legitimacy, and restraint as new determinants of deterrence. The findings suggest that South Asia’s stability now depends less on sheer capability and more on cognitive and diplomatic agility, marking the rise of a post-balance strategic order.
