The Case for Banning US Nuclear Weapons

The Global Nuclear Dilemma: History, Proliferation, and the Push for a Ban

The debate over nuclear weapons is as much about morality as it is about geopolitics. For decades, the world has lived under the shadow of “mutually assured destruction,” a precarious balance where the possession of nuclear arsenals is intended to deter conflict. But, the historical reality of these weapons—and the ongoing struggle to eliminate them—continues to spark intense international debate.

The Historical Precedent: Hiroshima and Nagasaki

The operational use of nuclear weapons is a singular event in human history. On August 6 and 9, 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima, and Nagasaki. These attacks ended World War II but resulted in catastrophic loss of life, with estimates ranging from 150,000 to 246,000 people killed, the majority of whom were civilians, according to records from the National Archives and other historical sources.

This precedent created a global trauma that fueled the early disarmament movements. The sheer scale of destruction led many to argue that such weapons are inherently indiscriminate and therefore illegal under international humanitarian law.

The Current State of Nuclear Arsenals

Despite the horrors of 1945, the world did not move toward immediate disarmament. Instead, a nuclear arms race emerged. By 2026, the landscape of nuclear possession remains concentrated among a few powerful actors.

Who Holds the Power?

According to the Federation of American Scientists, nine countries possessed roughly 12,187 warheads at the beginning of 2026. The distribution is heavily skewed: the United States and Russia together possess approximately 86% of the world’s total inventory.

The nuclear-armed states generally fall into three categories:

• NPT Recognized: The U.S., Russia, China, France, and the United Kingdom.
• Non-NPT Declared: India, Pakistan, and North Korea.
• Non-Declared: Israel maintains a policy of “nuclear ambiguity” but is widely understood to possess an arsenal.

The Legal Battle: NPT vs. TPNW

The international community uses two primary frameworks to manage nuclear threats, and they often clash in philosophy.

The Non-Proliferation Treaty (NPT)

The NPT is the cornerstone of global nuclear diplomacy. It is based on a three-pillar bargain: non-proliferation, the right to peaceful energy, and a commitment by nuclear-armed states to eventually pursue disarmament. However, critics argue the NPT is flawed because it creates a “two-tier” system where a few states are permitted to keep weapons while others are forbidden from acquiring them.

The Treaty on the Prohibition of Nuclear Weapons (TPNW)

In response to the slow pace of the NPT, the TPNW was developed to create a comprehensive ban on nuclear weapons, similar to the bans on chemical and biological weapons. As of September 2025, 99 states had signed or ratified the TPNW, representing over half of the world’s countries. According to the Nuclear Weapons Ban Monitor, the share of states supportive of this ban has risen to 70.6%.

“Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation. We need the Treaty on Non-Proliferation of Nuclear Weapons as much as ever.” António Guterres, UN Secretary-General

Looking Forward: The 2026 Review Conference

The world is currently focused on the 11th Review Conference of the Parties to the NPT, taking place from April 27 to May 22, 2026. This summit arrives at a time of heightened tension, with diplomats attempting to prevent further proliferation amidst global instability.

The central question for the future remains: Can the world move from a strategy of “deterrence”—where peace is maintained through fear—to a strategy of “abolition,” where nuclear weapons are banned entirely? While the TPNW shows a growing moral consensus, the reality of military stockpiles suggests that the road to a nuclear-free world remains long and fraught with political obstacles.
