Global Security and Nuclear Disarmament

The expiration of the New START Treaty marks a pivotal moment in global security dynamics. With the U.S. and Russia controlling the majority of the world's nuclear arsenal, the treaty's lapse undermines strategic stability and complicates international non-proliferation efforts. This situation poses challenges to India's strategic goals, as it seeks to maintain regional security and contribute to global disarmament dialogues. The absence of a successor agreement raises the risk of an arms race, potentially impacting global peace rankings and economic stability.
