The DMZ and North Korea

What Is the DMZ?
The Korean Demilitarized Zone (DMZ) is a strip of land running 160 miles (250km) across the Korean Peninsula that serves as a buffer zone between North Korea and South Korea. It passes just 30 miles north of Seoul but is one of the most heavily guarded borders in the world. It divides the Korean Peninsula approximately in half roughly near the original border at 38°N (the 38th parallel), the line that divided North and South Korea at the end of World War II. The Demilitarized Zone incorporates territory on both sides of the cease-fire line as it existed at the end of the Korean War (1950-1953), and was created by pulling back the respective forces 1.2 miles along each side of the line.
The armistice that ended hostilities was signed here in 1953, but, as an official peace treaty was never signed, the two sides have officially been at war for over seven decades.
A Brief History of the DMZ
With Japan’s surrender to the Allies ending World War II in 1945, Korea gained its independence after 35 years of colonization by Japan. The United States and the Soviet Union agreed to a joint temporary occupation of the Korean Peninsula with the US administering the southern part and the USSR administering the northern part.
The zones were split at the 38th parallel, an arbitrary line on the map chosen because it divided the country roughly in half. The division and international administration was supposed to be temporary until Koreans were considered ready to govern by themselves, but with the onset of the Cold War and growing suspicion between the US and USSR the two sides failed to come to an agreement that could establish a unified Korean government and state.
Instead the Republic of Korea (ROK), supported by the United States, was established in 1948 in the south while the Democratic People’s Republic of Korea, supported by the Soviet Union, was established soon after in the north, with both sides claiming sovereignty over the whole peninsula.
On June 25th, 1950, the new North Korean Army invaded across the 38th parallel in an attempt to quickly reunify the Korean peninsula by force. They nearly succeeded, but US-led international intervention changed the course of the war. The conflict devastated the Korean peninsula for three years and killed three million people. After the conflict reached a stalemate close to the 38th parallel, the Korean Armistice Agreement was signed on July 27th, 1953 between the United Nations Command, North Korea, and China to establish a ceasefire.
Each side agreed to move their troops back 2,000m (1.24 miles) from the front line to create a demilitarized zone, establishing a 2.5 mile wide buffer with established rules of conduct. The Military Demarcation Line (MDL) runs through the middle of the DMZ and indicates where the front was when the agreement was signed.
More than seven decades later, both sides still stand guard on either side of the DMZ, two large armies on constant alert for potential aggression from the other side. The arbitrary division that in 1945 everyone thought would be temporary has ended up with one of the most impermeable borders in human history.
The Security Status at the DMZ
The border between North and South Korea is one of the most heavily guarded stretches of land in the world. The DMZ, littered with scores of mines and barbed-wire fences, is almost impossible to cross, except at the Joint Security Area (JSA). The JSA is a special zone inside what is known as the "truce village" of Panmunjom, about 35 miles north of Seoul. Every year, when it is open to tourists, thousands of people visit the JSA for a chance to see North Korean soldiers standing at attention just dozens of feet away and to officially step into North Korean territory inside a United Nations Command administered conference room that straddles the military border.
A visit there feels like military theater, with stern warnings from the South Korean soldiers under United Nations Command not to make gestures at their counterparts. Since demarcation, the DMZ has had numerous incidents and incursions by both sides, although the North Korean government typically doesn’t acknowledge direct responsibility for any of these incidents.
Human Rights and Repression in North Korea
North Korea is one of the world's most repressive states. The government restricts all civil and political liberties for its citizens, including freedom of expression, assembly, association, and religion. It prohibits all organized political opposition, independent media, civil society, and trade unions. The government routinely uses arbitrary arrest and punishment, torture in custody, forced labor, and executions to maintain fear and control across the country. Beyond the DMZ, North Korea is a highly controlled country where human rights are routinely violated.
The international community has continued to press the North Korean government to expand its engagement with United Nations human rights mechanisms, including action on findings of the UN Commission of Inquiry (COI). The COI report shows that the country has committed crimes against humanity including extermination, murder, enslavement, imprisonment, rape, sexual violence, forced abortion, and other heinous crimes. The citizens of North Korea require a lot of help and support from the international community in order to attain a better life.
The North Korean people face a brutal and repressive government that isolates them from the world and denies their most basic human rights. But you can help to create change. At Liberty in North Korea (LiNK), we help North Korean refugees escape through a 3,000-mile secret rescue route and empower North Koreans who have reached freedom to be changemakers, advocates, and leaders on this issue.

North Korean Soldiers in Russia-Ukraine War
Insights from LiNK’s Chief Strategy Officer, Sokeel Park

Since the end of last year, there have been multiple credible reports of a significant number of North Korean troops being killed and wounded while fighting against Ukrainian forces in Kursk. More recently, there have been media interviews with two North Korean POWs' being held in Ukraine and reports of additional reinforcements being sent to Russia. Kursk is a Russian region bordering Ukraine where Ukrainian forces have held territory since last summer, aiming to change the dynamics of the war and hold a bargaining chip for peace negotiations.
These North Korean soldiers were sent to Russia by Kim Jong Un last autumn as part of his support for Putin’s war. In return, Russia is thought to be providing North Korea with oil, military technology, food and cash.
Kim Jong Un’s Goals and How The World Can Respond
Since the first reports of this unprecedented deployment of over 10,000 North Korean troops to a foreign war we have been in discussions with the Ukrainian Embassy in Seoul, the US government, and Ukrainian civil society representatives regarding policy recommendations and potential responses.
Whilst it is clear that Kim Jong Un does not care about the tragic loss of life of young North Korean men in the trenches of Kursk, he does care about maintaining control over North Korean people’s information environment.
At every opportunity we will continue to encourage relevant governments to increase information access initiatives with strategic messaging targeting North Korean troops in Russia, overseas North Koreans, and audiences inside North Korea. The objectives are to decrease North Korean soldiers’ willingness to fight for Putin, encourage surrender and defection, prevent avoidable loss of life, and increase political costs for Kim Jong Un to continue his military support for Putin.
Treatment of North Korean POWs
We also call on the media to protect the rights, dignity and identity security of any captured North Korean POWs who may be made available for interviews. The North Korean military does not educate its soldiers on its rights as POWs, and information released through such interviews may endanger the soldiers themselves and family members back in North Korea. The Geneva Convention also protects POWs against being subject to public curiosity, meaning interviews must be truly voluntary with fully informed consent, and not exploit the POWs status or conditions. We have discussed these issues directly with relevant journalists, but it is regrettable that in the race to be first some media’s ethical standards have dropped.
The Future of North Korea
The North Korean government’s threats to international security are real, and they dominate the news headlines regarding the country. But we should remember that the North Korean soldiers dying on the battlefield come from the same communities as North Koreans that have come to freedom with us, are now enthusiastically learning English in Seoul, advocating for North Korean human rights at the UN, and working with us to challenge the North Korean government’s control over information.
It will only be when North Korea opens up and all North Korean people gain their basic freedoms that North Korea can have leadership that values North Korean lives. When that happens all of these issues, including the North Korean government’s threats to international security, can be resolved. Thank you for your ongoing support for this vision.
