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.

If you want to go even further back, here's how North Korea came to be!
668 A.D: Ancient Korea
People have been living on the Korean peninsula since prehistoric times, slowly developing their own distinct culture and civilization. The Korean people were first united by the Silla Dynasty in 668 A.D. Since then, Korea has had to contend with the expansionist ambitions of its neighbors.
1910: Japan Colonizes Korea
In 1910, the Chosun Dynasty ended with Japan’s annexation and colonization of Korea. Koreans remember the Japanese colonial rule as a brutal experience. Resistance groups formed in Korea and China, mostly adopting leftist politics in reaction to the right-wing Japanese administration. Memories of the Japanese Imperial Administration’s oppression continue to haunt relations between the people of both Koreas and Japan today. Korea also began to modernize during this period, and the city of Pyongyang in particular became a vibrant center for Christianity and western culture.
1945: The Division of the Korean People
Following Japan’s defeat in 1945 the Soviet Union and United States agreed to split the post-war control of the Korean peninsula between themselves. On August 10, 1945 two young U.S. military officers drew up a line demarcating the U.S. and Soviet occupation zones at the 38th parallel. The divide should have been temporary, a mere footnote in Korea’s long history, but the emergence of the Cold War made this a seminal event. Seeking to ensure the maintenance of their respective influences in Korea, the U.S. and USSR installed leaders sympathetic to their own cause, while mistrust on both sides prevented cooperation on elections that were supposed to choose a leader for the entire peninsula. The United States handed control over the southern half of the peninsula to Syngman Rhee, while the Soviet Union gave Kim Il-sung power over the north. In 1948, both sides claimed to be the legitimate government and representative of the entire Korean people.

1950: The Korean War Begins
June 25, 1950
In 1950, Kim Il-sung attempted to unify Korea under his rule through military force, starting the Korean War. By far the most destructive and divisive event in Korean history, the war altered the life of almost every Korean person. Some historians claim that the U.S. military dropped more napalm on urban centers in Korea than Vietnam. The bombing campaigns reduced Pyongyang to rubble, and North Korea’s population was reduced by 10%.
July 27, 1953
Both sides eventually signed the armistice ending major hostilities in 1953. The DMZ (demilitarized zone) was established at almost the same position as the border before war broke out, separating millions of families caught on opposite sides of the border.
1953-1970s: Building a Stalinist State
From 1953 to the 1970s North Korea was considered by some outside observers to be a successful state. During this period, many North Koreans were actually better off than their southern brethren.
Kim Il-sung remodeled North Korean society along the lines of Juche—North Korea’s radically nationalistic ideology promoting Korean autonomy. The state-seized control of all private property and organizations. Officially, everything in the country, from businesses to the clothes on one’s back, belonged to the North Korean state. The regime rebuilt Pyongyang as a socialist capital and erected numerous monuments to Kim Il-sung, part of nationwide efforts to build a cult of personality to secure obedience by the people. The state took control of all media and restricted international travel. Kim Il-sung also worked constantly to centralize power under the Workers’ Party of Korea under his rule, and implemented a perpetual purge to rid the country of potential internal opponents to his rule.
Songbun
Massive inequalities began to emerge in North Korean society. The regime introduced the songbun system, which is still in place today. Under this system the entire population were sorted into different social classes according to one’s perceived loyalty to socialism and the regime. This classification determined the course of people’s lives. One’s songbun dictates the schools one can attend, the occupations one can be placed in, and even where one can live.At the time, the regime expelled around a quarter of the population of Pyongyang to the outer provinces for being of low songbun. For more on songbun, see this blog post.
The regime silenced anyone who opposed the system with extreme prejudice. Free speech became an offense punishable by imprisonment or even death. Worse, when one was arrested, up to three generations of their family would be sent to political prison camps. The regime instructed children to inform on their parents, and neighbors to inform on each other. Under these conditions, the North Korean people became fearful and distrusting of each other.
Stagnation
By the 1970s, the initial gains of postwar reconstruction and modernization had dissipated, and Kim Il-sung’s ideologically driven governance failed to produce prosperity. North Korea was also highly dependent on trade and aid from the Soviet Union and the Eastern bloc, so when the economies of those countries began to decline it greatly affected North Korea’s economy. The people’s quality of life stagnated in the 1980s and began to decline until the collapse of the USSR in 1991, at which point the North Korean socialist command economy stopped functioning. Poor agricultural policies and environmental mismanagement increased vulnerability to extreme weather conditions and brought increasingly meager crop yields. To make matters worse, the regime had lost allies to fall back on when the economy failed. North Korea’s reserves were quickly running out. These were the circumstances the country found itself in when Kim Il-sung died in 1994.
Economic Collapse
Kim Jong-il took power in the post-Cold War era when North Korea was on the brink of disaster. Realizing the need to handle both external and internal threats, Kim Jong-il instituted a “military first” policy that prioritized the military and elites over the general population to an even greater extent than before. This policy made the coming crisis even worse for the average North Korean. Many North Koreans blame Kim Jong-il’s leadership for the famine. In reality, Kim Jong-il’s policies exacerbated a crisis that was long in the making.
The economic collapse and subsequent famine in North Korea had its peak in the mid-to-late 1990s. It is estimated that up to one million people died—roughly 5% of the population. Even many of those that survived suffered immensely. Starvation in childhood has stunted the growth of an entire generation of North Koreans. The North Korean government had to lower the minimum required height for soldiers because 145 cm (4 feet 9 inches) was too tall for most 16-17 year olds.
In Barbara Demick’s book “Nothing to Envy”, a North Korean doctor tells of how even she became desperately hungry. After fleeing to China, she discovered a bowl of food left out for a dog. Upon examining the white rice and generous chunks of meat, she concluded that “dogs in China ate better than doctors in North Korea.”

Social Changes
The collapse of the command economy led to widespread social changes. The need for food drove the North Korean people away from the regime’s control, as when the government stopped providing food, the survivors found other ways to feed themselves. People foraged and sold anything they could to buy food at small, illegal markets that began to spring up, creating a process of bottom-up marketization. Some fled to China, leading to a wave of refugees from North Korea, while information about the outside world slowly began to flow back into the country. Some resorted to prostitution or crime. What was once a highly ordered and controlled society gave way to a disorganized and fluid society, with new independent paths to wealth and power for those who defied the regime and pursued the markets. These social effects would continue even after the worst of the famine had passed.
2000s: The People & Markets Prove Their Resilience
By the early 2000s, the people began to recover. The markets, which initially emerged as a survival mechanism, gradually grew to encompass a broader range of goods and services and became better established. The markets today are the major source of food for ordinary North Koreans. South Korea also adopted the “Sunshine Policy”, in which it gave unconditional aid to North Korea, and increased economic cooperation between the Koreas. Established in 2003, the Kaesong Industrial Complex just north of the DMZ was part of this policy and now allows South Korean companies to hire over 50,000 North Korean workers. China also gradually strengthened its economic relationship with North Korea, and today is by far North Korea’s most important economic and political partner. Nevertheless, ordinary North Koreans continue to face the severe challenges of chronic food shortages and grinding poverty, while their basic freedoms are curtailed by a repressive regime whose number one concern is staying in power.
Always uneasy about the growth of the markets, in late 2009 the regime made their most drastic attempt to restrain the markets to date: a currency reform aimed at wiping out private wealth. The resultant market disruption and rapid inflation reversed the people’s hard-won progress, and even regime projects were derailed. North Korean refugees have described this as a watershed moment in their diminishing belief in the regime, with anti-regime sentiment so strong that it even rose to the surface in some communities. It is now absolutely clear to the regime that the markets are a fact of life they must learn to live with.

Now: The Third Kim Era
In December 2011, Kim Jong-il died and his son Kim Jong-un inherited control of the nation. Thought to be just 27 or 28 years old at the time of his succession, Kim Jong-un was largely unknown to the North Korean people as well as to the outside world. North Koreans that escaped the country in 2011 told us that there had not been a lot of propaganda about Kim Jong-un during that year. By contrast, Kim Jong-il was much better known to the North Korean people when he came to power in 1994.
In his first years in power, Kim Jong-un has implemented a new PR style that has portrayed him as a modern version of his grandfather, while purging, demoting and promoting regime officials to secure his power base. The new leadership also moved to crack down on illegal cross-border movement and the inflow of foreign media, increasing repression in the border regions and reducing the number of defectors who managed to make it to South Korea by almost half. Meanwhile, there have been signs of cautious experimentation with economic liberalization in order to adapt to the reality of the entrenched de facto market economy inside the country.
North Korea’s history is far from over. In fact, it may be entering its most interesting phase. The people are becoming increasingly empowered and the grassroots changes spreading across North Korean society are steadily increasing the people’s physical and psychological independence from the regime, making the system as it is currently structured unsustainable. We cannot know the pathway that North Korea’s change and opening will take, but change and opening will happen, and the future of North Korea will be increasingly driven by the North Korean people themselves.
