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!
A North Korean Refugee’s Journey - Pursuit of the Freedom to Learn

In partnership with the British Council, LIEP aims to cultivate participants’ communication and critical thinking skills in English. LIEP is complementary to our broader LiNK English Language Program (LELP), which supports speakers of all proficiency levels.

I was born in North Korea—a place where identities are imposed, voices are silenced, and dreams are tightly confined. There, schooling is not a pathway to opportunity but a means of indoctrination, designed to enforce obedience and suppress individuality. But thanks to my mother’s courage, I never had to undergo that system. She made the bold decision to keep me out of school in North Korea. At age eight, I escaped to China to reunite with her, beginning a journey that would define not only my identity but also my deep, lifelong yearning to learn.
In China, my mother obtained a false identity for me so I could enroll in school. That first day in a rural classroom marked the beginning of a different kind of life. I was behind, anxious, and constantly aware of our fragile situation.
For the first time, however, I was learning not to obey—but to think.
A year later, we moved to Beijing. There, I stepped into a world I had never imagined—one of academic rigor, intellectual freedom, and cultural diversity. It was in that environment that I first witnessed how learning can transform a person. Each lesson, each classroom conversation, opened doors not only to knowledge but also to self expression, confidence, and hope.
One winter afternoon in 2010, I was on my way to the bookstore, backpack heavy on my shoulders. Beijing was bleak and cold that year. Snowflakes fell softly, only to be crushed by cars and vanish into the grime of the streets. That scene reflected my life: I bore a name I couldn’t speak aloud, fears I couldn’t share, and a fragile existence that felt quietly lonely.
Inside the bookstore, warmth greeted me. I wandered through the aisles, searching for a quiet corner to rest. Then, I saw it—a book with a black-and-white cover, its portrait etched in solemn ink. The man’s composed expression exuded a power I longed for. I picked it up, almost unconsciously.
“I Have a Dream.”
“I have a dream that one day... people will not be judged by the color of their skin but by the content of their character.”
“This is the time to make real the promises of democracy.”
“We will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.”
These weren’t just words. They were light, seeping through a crack I hadn’t known existed. In a world that had taught me to stay small and silent, they spoke to a part of me I had hidden away. For the first time, I felt truly seen—not for where I was from or what I looked like, but for my thoughts, my voice, and the quiet strength I carried within.
Later, after arriving in South Korea, I faced new challenges. Though I had returned to my cultural roots, I felt out of place. I was older than my classmates, unfamiliar with many social norms, and unsure of how to fit in. But with time, I began to build friendships and navigate this new society. Again, learning was central—it provided not just academic skills but also the social space to grow and belong.
During university, I studied abroad in Texas. It was my first experience in a Western classroom. I was struck by the openness, the individuality, and the value placed on diverse opinions. Being among students from different backgrounds showed me how perspectives can differ—and how that difference enriches everyone.
Wherever I was—in China, Korea, or the United States—the classroom was where I grew the most. It was where I stepped outside my comfort zone, gained confidence, and slowly came to understand who I was becoming.
Across all these countries, I’ve developed not just a global perspective but a deep appreciation for the transformative power of learning. In each setting, the classroom became both a battlefield and a sanctuary. I struggled, but I also discovered. I learned new languages, absorbed new worldviews, and came to realize that I was more than a refugee or survivor. I was a thinker, a student, and a human being with agency.
And then I understood something deeper: My story is rare—but it shouldn’t be. There are still millions of children in North Korea growing up without the right to question, to dream, or to imagine a world beyond their borders. They deserve more than silence or sympathy. They deserve the same chance I had—to envision a different future and be equipped to pursue it.
That’s why I’m sharing my story through Liberty in North Korea. Because stories hold power. They build bridges, shatter stereotypes, and create connections.
North Korean people are not just victims. They are potential scholars, leaders, creators, and changemakers—if only they are given the freedom to grow.
My dream is to one day build a global school for children who, like me, come from hardship but brim with promise. I want to help others discover the same sense of identity and possibility that learning gave me. Until then, I will continue to advocate, teach, and connect.
If you’re reading this, I hope you’ll join me. Learn more. Speak up. Share stories. Support organizations like LiNK that are fighting to empower North Korean people with freedom, dignity, and opportunity.
Because when you invest in a child’s education, you’re not only changing one life—you’re challenging an entire system and planting seeds for a freer world.
Opportunities like LiNK’s Intensive English Program (LIEP) are helping North Koreans succeed in resettlement, reach their goals, and lead change on this issue. Your support can help us continue to make an impact in the lives of North Korean refugees.
