North Korea's nuclear weapons program has long been a source of concern for the international community, with the country conducting its first nuclear test in 2006. Since then, North Korea has made significant advancements in its nuclear capabilities, including the development of intercontinental ballistic missiles (ICBMs) and the production of miniaturized nuclear warheads that can be mounted on missiles. Despite facing international sanctions and condemnation, North Korea continues to expand its arsenal, posing a threat to regional stability and global security. One particular area of concern is the potential impact of an electromagnetic pulse (EMP) attack, which could be used to knock out electrical grids and cause widespread disruption. While the effectiveness of such an attack remains uncertain, it underscores the urgent need to address the North Korean nuclear threat and find a path towards denuclearization and peace on the Korean Peninsula.

What You'll Learn
North Korea's nuclear weapons capabilities
In 1985, North Korea signed the Nuclear Non-Proliferation Treaty (NPT) as a non-nuclear weapon state. However, in 1993, the International Atomic Energy Agency (IAEA) raised concerns about discrepancies in the country's plutonium stockpiles, suggesting that North Korea had diverted plutonium from its civilian program. Despite being provided with evidence, North Korea refused to cooperate with the IAEA's requests for clarification. As a result, the agency's Board of Governors determined that North Korea was in non-compliance with its NPT-required safeguards obligations.
In 1994, former US President Jimmy Carter and North Korean leader Kim Il Sung negotiated the Agreed Framework, where North Korea committed to freezing its plutonium-based weapons program in exchange for energy assistance. However, this agreement broke down during the Bush administration due to North Korea's acknowledgment of a secret uranium enrichment program and the US's decision to halt its support. In response, North Korea announced it would restart nuclear activities and withdrew from the NPT in 2003.
Since then, North Korea has conducted six nuclear tests between 2006 and 2017, with the latest being its sixth nuclear test explosion in September 2017, assessed to be a hydrogen bomb with an estimated yield of 140-250 kilotons. In July 2017, the US estimated that North Korea would have a reliable nuclear-capable intercontinental ballistic missile (ICBM) by early 2018. Indeed, in November 2017, North Korea tested an ICBM that analysts estimated was capable of reaching the continental United States.
North Korea has continued to advance its nuclear weapons program, and in 2023, it unveiled the Hwasan-31 tactical nuclear bomb with at least 10 warheads. In December 2023, it launched an ICBM (a Hwasong-18) that could hit any target within the United States mainland, according to South Korea and Japan. As of January 2024, it is estimated that North Korea possesses around 50 nuclear weapons and has the fissile material for an additional 40-60 weapons.
The international community has taken a unified stance against North Korea's nuclear weapons possession, as reflected in multiple UN Security Council resolutions. Despite strong opposition, North Korea has sought recognition as a nuclear power since 2013 and passed a law in 2022 declaring itself a nuclear weapons state, rejecting any possibility of denuclearization.

EMPs (electromagnetic pulse weapons)
An electromagnetic pulse (EMP) is a short-duration pulse of energy that can be naturally occurring or artificially generated. Naturally, EMPs can occur as a result of lightning, solar flares, or meteoroid impacts. Artificially, EMPs can be generated through the use of nuclear or non-nuclear means.
Nuclear electromagnetic pulses (NEMP) are created by nuclear explosions and can produce a secondary pulse due to particle interactions with the Earth's atmosphere and magnetic field. This is known as a high-altitude electromagnetic pulse (HEMP) and can cover a wide area, potentially knocking out electronic equipment and disrupting communications.
Non-nuclear electromagnetic pulses (NNEMP) are generated without the use of nuclear technology. Devices that can create NNEMPs include capacitor banks, microwave generators, and flux compression generators. NNEMPs typically have a shorter range than NEMPs and are often carried as payloads on bombs, cruise missiles, or drones.
The threat of North Korea potentially using an EMP attack has been a concern for various administrations. Former CIA Director Jim Woolsey warned that North Korea could detonate a nuclear device in a satellite orbiting miles above the Earth, creating an EMP that could knock out a significant portion of the electric grid. However, most experts believe that North Korea is more likely to use nuclear weapons in a direct attack rather than an EMP attack.

North Korea's missile range
North Korea has been developing its missile and nuclear capabilities since at least 2009, when it claimed to have put a satellite into low Earth orbit. The country has conducted numerous missile tests, with the number increasing steeply under Kim Jong Un's leadership since 2011. In 2012, North Korea agreed to a moratorium on long-range missile tests as part of negotiations with the United States. However, this agreement was short-lived, as North Korea conducted a long-range missile test in April 2012.
North Korea's missile arsenal includes various short-range, intermediate-range, and intercontinental ballistic missiles (ICBMs). The Hwasong-12, with a range of up to 4,500 km, can reach the US island of Guam in the Pacific. The Hwasong-14 has an estimated range of 8,000-10,000 km, which puts New York within reach. The Hwasong-15, with a range of 13,000 km, can target any part of the continental United States. Additionally, the Hwasong-17 is believed to have a range of 15,000 km or more and could carry multiple warheads.
North Korea's missile tests have raised concerns among the international community, leading to sanctions by the United Nations and individual nations. The country's missile and nuclear development has been closely monitored by the United States, South Korea, and Japan, who are concerned about the potential threat to their territories. In 2017, the US estimated that North Korea would have a reliable nuclear-capable ICBM by early 2018. This prediction came true, with North Korea successfully launching an ICBM in March 2022, its first successful test since 2017.
North Korea's missile program has also been linked to Russia's war in Ukraine, with concerns that North Korea could provide Russia with weapons. Additionally, Russian and North Korean soldiers have fought alongside each other, and Russia has praised the "heroism" of North Korean troops. The collaboration between the two countries has raised concerns about the potential impact on global security and peace.

South Korea's defence capabilities
South Korea has one of the largest and most powerful standing armed forces in the world, with a reported strength of 3,600,000 personnel in 2022 (500,000 active and 3,100,000 reserve). The South Korean military is currently ranked as the 5th most powerful military in the world.
The country's military forces are responsible for maintaining the sovereignty and territorial integrity of the state and also engage in peacekeeping operations, humanitarian and disaster relief efforts worldwide. South Korea's military strategy has become increasingly offensive over the past decade, with the country investing in stealthy drones that could penetrate North Korea.
South Korea's defence industry is the main supplier of armaments to the Republic of Korea's Armed Forces. The country began manufacturing its own weapons following industrialization and military modernization efforts. South Korea now has a robust defence industry and is the world's 8th largest weapons exporter.
South Korea's shipbuilding expertise gives it an advantage in constructing larger warships. The country has the infrastructure, technologies, and skills to construct warships and has been pursuing a blue-water navy. South Korea's desire to establish a blue-water navy is partly due to its territorial disputes with China and Japan.
South Korea's military has formulated a strategy known as the "three-axis system," which includes preemptive strikes targeting North Korea's nuclear and missile facilities, the Korea Air and Missile Defense (KAMD) system, and the Korea Massive Punishment and Retaliation (KMPR) plan. This strategy reflects South Korea's need to deter an increasingly nuclear-capable North Korea.

North Korea's chemical weapons stockpile
North Korea's energy problems have been a long-standing issue, with the vast majority of its population lacking consistent access to electricity. Despite this, North Korea is a net energy exporter, primarily utilising hydropower and coal as its energy sources.
Now, onto the main topic: North Korea's chemical weapons stockpile.
North Korea is known to possess a significant stockpile of chemical weapons, estimated to range from 2,000 to 5,000 metric tons. While the country has never publicly confirmed the existence of its chemical weapons programme, various intelligence agencies, including those from the US and South Korea, have assessed that North Korea has a diverse range of lethal chemical agents. These agents include nerve agents, blister agents, blood agents, vomiting agents, and choking agents. The country is also believed to have the capability to deliver these chemical weapons through various systems, including ballistic missiles and aircraft.
The origins of North Korea's chemical weapons capabilities can be traced back to the late 1960s and early 1970s, when it received assistance from the Soviet Union and China in developing its chemical industry. By the late 1980s, North Korea's capabilities had expanded significantly, with reports indicating possession of up to 250 metric tons of chemical weapons, including mustard gas and nerve agents.
In addition to its chemical weapons, North Korea is also known to possess biological weapons, such as anthrax, smallpox, and cholera, and is actively pursuing the development of nuclear weapons.
