Modern Threat of Nuclear Weapons - UPSC International Relations
What is Modern Threat of Nuclear Weapons in UPSC International Relations?
Modern Threat of Nuclear Weapons is a key topic under International Relations for UPSC Civil Services Examination. Key points include: Nuclear weapons have evolved from 15 kt (Hiroshima) to 50 Mt (Tsar Bomba), an increase of over 3,800 times in destructive power.. This exponential increase in yield occurred primarily during the Cold War arms race.. Modern nuclear arsenals, while often using smaller warheads, employ advanced delivery systems like MIRVs for strategic impact.. Understanding this topic is essential for both UPSC Prelims and Mains preparation.

📖 Introduction
The Evolving Threat of Nuclear Weapons
The destructive potential of nuclear weapons has undergone a dramatic escalation since their first use. Understanding this evolution is crucial for comprehending modern global security challenges.
The first atomic bomb, dropped on Hiroshima in 1945, had a yield of approximately 15 kilotons (kt). This single weapon caused unprecedented devastation.
Escalation in Destructive Power
Modern nuclear arsenals possess capabilities far exceeding those of early atomic bombs. Technological advancements have led to the development of thermonuclear weapons, also known as hydrogen bombs, with significantly higher yields.
An example of this increased power is the Tsar Bomba, tested by Russia (then the Soviet Union) in 1961. This weapon achieved an estimated yield of 50 megatons (Mt).
To put this in perspective, the Tsar Bomba was over 3,800 times more powerful than the bomb dropped on Hiroshima. This stark difference highlights the exponential increase in destructive capacity.
Implications for Global Security
The existence of such powerful weapons necessitates robust international efforts for non-proliferation and disarmament. The potential for widespread destruction in a nuclear exchange remains a primary concern for policymakers worldwide.
UPSC Mains GS-II: When discussing nuclear threats, always mention the qualitative leap in destructive power from early atomic bombs to modern thermonuclear weapons. This demonstrates a nuanced understanding of the subject.
