Background

Overview

UPSC examines how major powers utilize defense sales as a tool of foreign policy, their impact on regional stability and power dynamics, the economic implications for exporting and importing nations, and the role of military alliances in global security architecture. It also touches upon the ethical and strategic dilemmas associated with such transfers.

Strategic arms sales are a critical component of a nation's foreign policy and defense diplomacy, involving the transfer of military equipment, technology, and services between countries. These sales often serve to strengthen alliances, project influence, enhance interoperability, and address security concerns of partner nations, while also having significant economic and geopolitical implications.
