From a strategic perspective, the Strait of Hormuz is a geopolitical weapon that can affect the future balance of power, international markets, and the outcome of conflicts

Why the Strait of Hormuz Has Become the Decisive Theatre in US–Iran Conflict?

“From a strategic perspective, the Strait of Hormuz is a geopolitical weapon that can affect the future balance of power, international markets, and the outcome of conflicts”

The Strait of Hormuz is no longer merely a maritime passage connecting the Persian Gulf with the Arabian Sea. It has evolved into the strategic fulcrum of global geopolitics — a narrow corridor where military power, energy security, economics, diplomacy, and great-power rivalry converge with dangerous intensity.

Trump, Xi and Cold War 2.0: Managing Rivalry in a Fragmented World

The complex US-China rivalry has evolved into "Cold War 2.0," entailing intertwined economic and strategic interactions amidst military posturing. Presidents Trump and Xi's approaches symbolize contrasting strategies: Trump’s transactional nationalism versus Xi’s strategic continuity. The geopolitical landscape remains multipolar, requiring nations to navigate pressures prudently while fostering selective partnerships and avoiding outright confrontation.

India’s Security Policy: From Regional Security to Global Stability

It was an honour to deliver a talk at the National Seminar organised by Bharatiya Vichar Manch and Gujarat University on the theme “India’s Global Role: Yesterday, Today and Tomorrow” at the prestigious Atal–Kalam Research Park, Karnavati, Ahmedabad, on 16 February 2026.

The seminar brought together scholars, researchers, strategic thinkers, academicians, and enlightened citizens from various parts of India for a meaningful deliberation on India’s evolving global role and strategic trajectory in an increasingly turbulent world order. I spoke on “India’s Security Policy: From Regional Security to Global Stability,” examining India’s geopolitical security perspective, military capabilities, and the interplay of hard power, soft power, and smart power.The discussions reflected both intellectual depth and national commitment towards understanding India’s emergence as a responsible global power.

I had the privilege of speaking on the subject “India’s Security Policy: From Regional Security to Global Stability.” The deliberation focused on the evolution of India’s strategic outlook, the changing geopolitical environment, the nature of contemporary conflicts, and the role of India as a stabilising force amid global uncertainty. The discussion also covered India’s strategic conduct in the context of past and present wars, diplomacy, and its relations with Pakistan, China, and the United States. The session concluded with a lively and engaging question-and-answer interaction.

Coexistence as Strategy in the India–China Reboot

My latest article in Business Standard Blueprint (Defence & Geopolitics) analyses how and why India and China have moved towards a limited tactical reset since late 2025. I argue that the current engagement “is a product of necessity amid global turbulence, not trust” and is best seen as “cautious re‑engagement, not reconciliation.” The reset offers breathing space from US tariff pressures and global uncertainty, but it does not resolve the underlying structural rivalry or the unresolved boundary dispute.
