Nuclear weapons are one of the deadliest and most destructive weapons ever created by humankind. The catastrophic humanitarian consequences of nuclear weapons cannot be overstated, and therefore, it is essential to take immediate and decisive action to eliminate these weapons from the world. In this article, we will discuss why we need to take action against nuclear weapons now and what steps can be taken to achieve this goal.

Why We Need to Take Action Against Nuclear Weapons Now

The Humanitarian Consequences of Nuclear Weapons

The use of nuclear weapons will have catastrophic consequences for humanity. Even a limited nuclear exchange between two countries could cause a global famine that could result in the death of over one billion people [2]. The use of nuclear weapons can also cause long-term environmental damage, such as nuclear winter, which could result in the extinction of many species and the destruction of ecosystems.

The Need for Multilateral Disarmament

The UK believes that the only way to achieve a world without nuclear weapons is through gradual multilateral disarmament [1]. Countries must work together to negotiate and implement disarmament measures that reduce the global nuclear stockpile.

The Treaty on the Prohibition of Nuclear Weapons

The Treaty on the Prohibition of Nuclear Weapons is a crucial roadmap toward the total elimination of nuclear weapons [4]. To date, there are 15 ratifications and 60 signatures. This treaty is a step towards a world free of nuclear weapons and has the potential to create significant changes in international law and policy.

The Importance of Public Support

The International Campaign to Abolish Nuclear Weapons (ICAN) is working to ensure that all governments condemn nuclear threats and prevent nuclear use [3]. ICAN needs strong public support for this message at all levels. The public can help reduce the risk of nuclear weapons use by raising their voices against nuclear weapons and nuclear threats.

The Responsibility of All States

Like climate change and pandemic disease, nuclear weapons pose a global problem and require a global response. Therefore, it is the responsibility of all states to confront and condemn threats to use nuclear weapons and to take action to reinforce the norm against their use [8]. The presence of an external threat is often cited as a reason for acquiring nuclear weapons [7].

Policy Implications

The growing likelihood of proliferation attempts from not just foes but friends and frenemies as well is a concern [9]. It is essential to understand why countries take different routes to nuclear development to develop appropriate policies that prevent nuclear weapons’ spread.


In conclusion, the humanitarian consequences of nuclear weapons are catastrophic and unacceptable. It is crucial to take action against nuclear weapons now and work toward their total elimination. Multilateral disarmament, the Treaty on the Prohibition of Nuclear Weapons, public support, and the responsibility of all states are essential components in this process. We must work together to prevent nuclear weapons use and ensure a safer and more peaceful world.
