In 2024, the world’s population surpassed 8 billion citizens. This is more than a 300 percent increase since 1950, which is an important year for global warming. It was this year when carbon-dioxide (CO₂) emissions began to increase dramatically—driving up the global temperature.

Today, the average American emits about 15 tons of greenhouse gases annually, while the average African emits less than 1 ton per year. The global mean is about 4.3 tons per person per year, a 4.8 percent increase over the previous year.

As the Bulletin of the Atomic Scientists points out, the planet is now feeling the devastating effects of the 1.1-degree Fahrenheit increase in global temperature since 1880. According to the Bulletin, recent global warming is responsible for the increased risk of wildfires, the rise of rare diseases, the decline in global crop yields, and may even cause a “mosquito-pocalypse.”

Nuclear weapons deserve a large share of blame for these events. Let me explain.

Nuclear Weapons and Climate Change

As the graph below illustrates, 1–2 percent of the global population, mostly civilians, perished annually because of war between 1600 and 1945. Since 1950, with the development and fielding of great-power nuclear arsenals, that number has declined to less than 0.1 percent.

It is no mere coincidence that the global population has increased 300 percent in only seven decades. The fielding of large nuclear arsenals by the United States and Russia ensured that the great powers and their allies would not engage in World War III, or any other great-power war, that historically ensured the planet did not become overpopulated. Built on a foundation of White privilege, nuclear deterrence created a fear of utter destruction, which completely eliminated great-power war and led to a marked decline in the frequency and severity of all conflict—causing the human population to explode. Thus, the check on population growth was removed.

These weapons not only limit war, but they also decrease defense expenditures and the resources required for reconstruction after war. For example, the United States spent almost half of the nation’s gross domestic product (GDP) waging a world war from 1942–1945. More recently, the United States spent at least $3 trillion fighting limited wars in Afghanistan and Iraq. However, because of the Soviet and American nuclear arsenals, American defense spending, as a percentage of GDP, averaged a mere 5 percent during the Cold War and is now at a low of 3.5 percent.

The consequence of this reallocation of wealth from conventional warfare was unprecedented economic growth, which not only allowed populations to increase but also allowed societies to improve the health, prosperity, and consumption of their citizens—dramatically reducing poverty and increasing the average life expectancy (62 percent). This prosperity also led to the most rapid increase in technological development in human history.

The population growth and human prosperity brought about by seven decades of effective nuclear deterrence may appear to be a net positive, but a closer look reveals that human prosperity comes at the cost of devastating increases in the rate of global warming. There are simply more humans generating more greenhouse gases than ever, and the problem is only getting worse. There is a solution.

Solving the Climate Change Problem

It is time for the United States to take the lead in nuclear disarmament. If the United States, Great Britain, and France disarm, Russia, China, and North Korea will surely follow suit. The global community can then pressure India and Pakistan to disarm as well.

This does not mean we must put an end to war. Nuclear disarmament properly allows the world to return to waging large-scale conventional wars, which regulate population growth and economic prosperity. Such wars will help bring man-made global warming to an end. For example, a war between the United States, Russia, and China—post nuclear disarmament—would optimistically eliminate 80–160 million people. The planet would receive a respite in CO₂ production not enjoyed since the COVID-19 pandemic lockdowns of 2020–2021.

The return to large-scale warfare will also ensure worldwide economic degrowth, which will further reduce overall greenhouse gas emissions. It is only through a less prosperous world that we can ensure global warming ends. Another equitable feature of this strategy is that population will be reduced among the richest, most consumptive nations, possibly leaving room for some modest increases in the developing world.

Some may balk at this solution because they believe a return to great-power wars is not necessary because green energy will solve the problem. Unfortunately,  green energy’s high cost, unreliable energy production, and visible failures in Texas, Germany, and elsewhere are likely to turn people against a degrowth strategy relying on a green energy transition. Despite our best efforts, renewable energy simply cannot meet the insatiable demand of a wealthier and healthier global population. A return to widespread warfare is the only feasible solution.

It is time we follow the advice of Jonathan Swift, who, in his pamphlet, “A Modest Proposal: For preventing the children of poor people in Ireland, from being a burden on their parents or country, and for making them beneficial to the publick,” courageously sought to solve the Irish poverty problem by encouraging the Irish to sell their children as food for the hungry. Making the world safe for war is an equally innovative approach to ending global warming and deserves the same consideration Swift’s proposal received. We must act before it is too late.

Postscript

For those wondering if this is a serious article, the answer should be obvious, no. The article employs a rhetorical technique, reductio ad absurdum or, as Jonathan Swift called it, satire, to make a point. In short, a world without nuclear weapons is prone to frequent great-power wars that create greater human misery. No amount of hope can change what history and human nature have, for at least five thousand years, shown to be true.

The Climate Change Consequences of Nuclear Weapons was originally published on Global Security Review.

Efforts to conventionally deter Iran failed with Iran-inspired fighting spreading from Gaza to the Red Sea, Yemen, Iraq, and Syria. Recently, three American soldiers were killed and 34 wounded in a drone attack by Iran-backed militants in northeastern Jordan, according to US Central Command. The Pentagon has reported more than 160 attacks by Iranian-linked militia groups on American bases and forces in the Middle East since Israel was attacked on October 7, 2023. These actions place immense pressure upon President Joe Biden to strike the sovereign territory of Iran, which Iranian leaders may view as an act of war.

Moreover, recent political decisions render the threatened use of sanctions against Iran’s nuclear program impotent. In February 2021, the Biden administration rescinded President Trump’s United Nations (UN) sanctions restoration. This was followed by President Biden’s decision to release $6 billion “in exchange for the release of five Americans detained in Iran” and another $10 billion in a sanctions waiver that grants Iran access to money from Iraq in exchange for electricity purchases.

Recently, Maj Gen Hossein Salami, the head of Iran’s Islamic Revolutionary Guards, said the country is not seeking war with America, but is not afraid of it either. Iran’s aggressive behavior certainly lends credence to the statement. Iran is emboldened by its allies and empowered by its proxies. This, of course, is backstopped by an eerie sense of confidence that Iran may soon become a nuclear power. In May of 2022, the UN’s International Atomic Energy Agency (IAEA) announced that “Iran has accumulated enough enriched uranium to build a nuclear bomb,” with a uranium stockpile enriched to 60 percent that had grown four times in just 90 days.

David Albright, a former UN weapons inspector and founder of the US Institute for Science and International Security, said that if Iran continues producing enriched uranium at the same rate, the regime will have enough weapons grade material to make 12 nuclear bombs within five months. Meanwhile, Iran successfully launched three satellites into space using a two-stage, liquid-fueled rocket. This achievement undoubtedly accelerates Iran’s ability to perfect and field a future intercontinental ballistic missile (ICBM), likely the regime’s preferred nuclear weapon delivery system.

The United States is now experiencing coordinated aggression. The Biden administration’s 2022 Nuclear Posture Review warns, “In a potential conflict with a competitor, the United States would need to be able to deter opportunistic aggression by another competitor. We will rely in part on nuclear weapons to help mitigate this risk, recognizing that a near-simultaneous conflict with two nuclear-armed states would constitute an extreme circumstance.”

Furthermore, the Department of State’s International Security Advisory Board recently warned in their Report on Deterrence in a World of Nuclear Multipolarity that the United States must be concerned that adversary states could engage in opportunistic acts if or when the United States is engaged in other conflicts.

The bipartisan America’s Strategic Posture: The Final Report of the Congressional Commission on the Strategic Posture of the United States also advised that the possibility of opportunistic or simultaneous multi-state aggression should no longer be construed as improbable. According to the report, “The new partnership between Russian and Chinese leaders poses qualitatively new threats of potential opportunistic aggression and/or the risk of future cooperative two-theater aggression.” Opportunistic aggression can translate to other hostile states like Iran and North Korea in league with Russia and China if they perceive American limitations in capability, capacity, or the will to fight with enough ferocity as to induce the fear to attack in the first place.

It appears that Iran is taking advantage of an already beleaguered United States that continues to support Israel in its war with Iranian-backed Hamas; exports arms, munitions, and intelligence to Ukraine; deters a hostile North Korea; and must endeavor to discourage Iran’s top oil importer (China) from invading Taiwan. All of these “fronts” are collectively testing American diplomacy, burdening the American taxpayer, challenging the American defense industrial base, negatively impacting military readiness, and now producing American casualties.

Killing Americans is a clear escalation and yet another indication that Iran remains undeterred by the current threat of American power. These acts are timed to take advantage of an overburdened America and are designed to frustrate American efforts within the region and ultimately convince the United States to abandon its Middle East interests and allies. National Security Advisor Jake Sullivan’s untimely proclamation on September 29, 2023, that “[t]he Middle East region is quieter today than it has been in two decades” was a complete misreading of the region.

Successful deterrence requires the consistent application of power. Deterrence messaging must not be muddled or muted. It must be clear, powerful, and credible. How is this done?

First, the Biden administration must immediately end sanctions relief of Iran. The United States can never fund its adversaries.

Second, the United States must take a systematic approach to eliminate the weapons, command and control, and supplies of Iranian proxies. They must not be allowed to threaten American and allied forces across the region.

Third, the United States must credibly communicate through strength by moving nuclear assets closer to the region. The United States seems content to use ballistic missile nuclear submarines (SSBN) to deter North Korea. An SSBN in the Arabian Sea would communicate a similar deterrence message.

Fourth, America must heed the warnings of opportunistic multi-state aggression and prepare a robust capability to address this very real and demonstrated threat. To do otherwise risks abandoning regional allies in conflict.

Fifth, America must not attack Iranian targets within sovereign Iranian territory unless President Biden and Congress are ready to declare war. What may be a regional conflict for the United States is a fight for survival for the Mullahs in Tehran.

Iran and its proxies are not deterred from attacking American forces, whether motivated by opportunistic aggression or existential circumstances. It is time to create a real sense of fear within the Iranian leadership. They must dread economic isolation, the destruction of proxies, and potential attack on what Iran holds most valuable—themselves and their nuclear facilities.

However, unless prepared to declare war, the United States must limit its retaliation to targets outside sovereign Iran. To attack Iranian soil would be a clear indication that deterrence has failed and could potentially lead to an all-out war. Restoring deterrence after such an event would come at a much higher cost.

Deterrence aims to make the adversary afraid to attack by creating a preferable condition of war avoidance. The goal is to convince the adversary that maintaining a peaceful status quo is the best option. Starting a war to prevent another war is a bad strategy, and it does not qualify as deterrence.
