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.
You can help make a difference in the lives of North Korean citizens by learning more about our organization, raising funds, advocating for the people of North Korea, starting a rescue team, or making a donation today!
I Watched K-Dramas Inside North Korea. They Gave Me the Courage to Escape | Hannah’s Story
How many times have you checked your phone today? Fifty? A hundred? Every time we look at the screen we are connected to the world around us and an endless stream of information—news, research, entertainment.
Now imagine waking up tomorrow in a place without the internet. A place where people are executed for sharing foreign media, and where families risk their lives just to stay in touch across borders.
For 26 million people in North Korea, this is their reality. And 7 years ago, I was one of them.
I was born in Hoeryong, a city in the northernmost part of North Korea near the Tumen River. Winters were brutal and there were frequent shortages of fuel and electricity.
My father was a high school physics teacher. He was quiet, loyal and diligent. His days started at 7am in the classroom and went late into the night, even on weekends. But despite his dedication, the monthly rations he received were not enough for our family.
So in order to survive, my mother began selling goods at the market. She wanted a better life for us, and that led her to do the unthinkable—escape North Korea. Three times she tried. Three times she was caught. Each time she was imprisoned and sent to a labor camp.
The prison camp was a living hell. My mother saw women waste away from hunger and die from simple illnesses. She was one of the lucky ones; her family brought her food and medicine, an act that made her a witness to the suffering of others.
I was just 13 when I first visited her, carrying a bowl of rice. In North Korea, it falls to families to provide for their imprisoned relatives.
Seeing my mother stand there like a criminal, her head bowed before the guard, I knew this wasn't right. I should have been in school, but instead, I was sneaking food to her, hiding from the stares of strangers.
We were being punished, but I didn't understand why. I felt wronged, and in my anger, I blamed her.
My mother had made a choice to save her family, but North Korean society saw her as a criminal. My father, who had led a quiet life as a teacher, was denied opportunities at work. Our family was labeled as traitors.
In 2013, on her fourth attempt, my mother finally escaped and made it to South Korea. She worked tirelessly to send money back to North Korea to help our family. She also slowly opened a window into another world.
Using a smuggled Chinese cell phone I was able to speak to my mother from time to time. And on our secret calls she shared with me new South Korean expressions and words she was learning. As she settled into a new society, despite numerous differences, she also recognized similarities between North and South Korea and its people, and reminded me that despite decades of division, we are still one people.
I secretly began watching South Korean sitcoms. I’ll never forget one called “High Kick 3.” In one episode, there was a story about a man who fell into debt and was being chased by collectors. But what shocked me was that his family wasn’t punished for it. In North Korea, if one person “sins” the entire family is condemned. But this showed me that in South Korea, life could be different. That even within a family, you were free to make your own choices.
This realization changed me and offered a glimpse of the vast world beyond North Korea. Information, even in the form of a sitcom, was hope. And it was worth risking everything for.
Meanwhile, I continued to face obstacles in my day to day life. I had learned how to code and use software like photoshop, and I dreamed of going to university after graduation. But because my mother had defected, I was rejected. So I used my computer skills to find work as a photographer and photo editor.
Hoping to advance my career, I volunteered for the "shock brigade," a group sent to do manual labor at dangerous construction sites. While others prayed they wouldn't get picked for this kind of work, I went willingly, thinking it could be my way to a promotion.
I was sent to the Samjiyon district, a place known for its harsh winters. For over a month, I demolished buildings in minus 40-degree weather without protective gear. Dust filled my lungs, and sweat froze my clothes solid. My only relief was being able to sleep in a crumbling basement.
When I returned, expecting the promotion I had been promised, my supervisor simply said, "Let's wait a little longer."
That was the moment I understood my mother. She had risked her life to escape because she was after something more fundamental than a better life. She wanted to live like a human being.
In 2019, I made the same choice and escaped. With the help of Liberty in North Korea, I made it safely to South Korea and reunited with my mom.
Freedom wasn’t as easy as I thought it would be. In North Korea, my tech and computer skills had helped me survive. I had always thought that “no matter where I go, as long as I have a computer, I’ll be fine.” But in South Korea, I struggled with something as simple as a new keyboard layout. In school, subjects like social studies felt foreign because I had grown up in a completely different education system with distorted versions of history and philosophy. My dream of going to college suddenly felt impossible.
Eventually I found my place in science. The formulas and equations in math, chemistry, and physics were the constant, unchanging truths I could always count on.
I decided to major in electrical engineering. It was rare for North Korean defectors to pursue this field. But I was determined to stay ahead and not fall behind in our rapidly changing world. Now my goal is to become an engineer who can help bridge North and South Korea’s science and technology industries when the two countries are one again.
More than ever, I see that information isn’t just about knowledge and convenience—it’s a lifeline. Without access to information, you can’t see a way forward, let alone build a future.
And right now, the people I left behind are more cut off than ever before. During the pandemic, North Korea closed its borders to an unprecedented extent. Soldiers along the border had shoot-to-kill orders for anyone trying to escape. Around 90% of the markets were forced to shut down, leaving families with barely enough to eat. The UN reported that nearly half the population—12 million people—faced food insecurity, while the World Health Organization rated North Korea’s access to medical care as the lowest in the world.
A few years ago, when my father became very sick, I was able to send him money for medicine and hospital care. But most North Koreans don’t have that chance. Without someone on the outside, they are not only cut off from resources and information, but from hope itself. For many, their future depends on a lifeline from the outside world.
Supporting North Korean people and protecting human rights cannot be put off.
We have an opportunity to be a lifeline for people inside North Korea today. To remind them that they have not been forgotten. With your support, we can rescue and support more North Korean refugees, and get more outside information and technology to people inside the country. And that information can empower North Koreans to not only see a way forward, but to ultimately determine their own future.
Despite the risks, North Koreans are quietly accessing foreign media and learning about life in the outside world. Increasing their access to uncensored information is one of the most effective ways to increase change inside the country.
Liberty in North Korea partners with North Korean defectors and engineers, like Hannah, to develop technology, content, and tools tailor-made for the North Korea context. Our goal is to empower North Koreans with information about the outside world, increasing their aspirations for social and economic progress, and building pressure for change and opening.
