The Korean War

1. The Korean War was a deeply rooted civil conflict, not a sudden, isolated event.

The point to remember is that this was a civil war and, as a British diplomat once said, “every country has a right to have its War of the Roses.”

A localized civil struggle. The conventional narrative of the Korean War starting abruptly on June 25, 1950, ignores the years of low-intensity conflict, border skirmishes, and political violence that preceded it. This was fundamentally an internal struggle between two incompatible social, economic, and political systems vying for the soul of a unified nation.

Deep historical roots. The origins of the conflict stretch back to the anti-Japanese guerrilla resistance of the 1930s in Manchuria, where the future leaders of North Korea cut their teeth. The post-World War II division merely catalyzed these pre-existing domestic tensions into a full-scale conflagration. Key elements of this internal struggle included:

• A revolutionary peasant movement demanding land reform and social equity.
• A conservative landed elite desperate to protect their wealth and status.
• A highly politicized police force inherited from the Japanese colonial administration.

Misunderstood by outsiders. By framing the war purely as a proxy battle of the global Cold War, external powers failed to comprehend the deep-seated local grievances driving the combatants. This fundamental misunderstanding led to strategic blunders and a tragic, prolonged stalemate that left the peninsula permanently divided.

2. The historical memory of the war is highly asymmetric between Korea and America.

Here, in essence, is the reason why Koreans remember, and Americans forget.

Asymmetric historical memory. For Americans, Korea is the "forgotten war," a gray, unpalatable stalemate sandwiched between the clear triumph of World War II and the cultural trauma of Vietnam. For Koreans on both sides of the DMZ, however, the war remains an open, bleeding wound that defines their daily existence and national identity.

The pain of remembrance. In North Korea, the memory of American saturation bombing is kept alive as a foundational myth of state survival and resistance. In South Korea, decades of military dictatorship suppressed the memory of state-sponsored massacres, which have only recently been unearthed by a democratized society. This asymmetry manifests in several ways:

• American popular culture largely reduced the war to the lighthearted, detached narrative of M*A*S*H.
• Korean families carry a deep, intergenerational grief and unresolved bitterness known as han.
• The physical landscape of both Koreas remains heavily marked by the scars of the conflict.

Willed amnesia. The American tendency to forget the war stems from its lack of a clear, victorious narrative and the uncomfortable truths of civilian casualties and allied atrocities. By burying the memory of the conflict, the United States has remained blind to the persistent motivations of its North Korean adversary.

3. The 38th parallel was an arbitrary, externally imposed division that ignored Korean history.

In justifying the American invasion of North Korea, however, the U.S. ambassador to the UN called the 38th parallel “an imaginary line.”

An arbitrary boundary. The division of Korea at the 38th parallel was a hasty, unilateral decision made by two American officers in August 1945 with a map and a tight deadline. This artificial line ignored over a millennium of unified Korean history, culture, language, and geographic integrity.

A recipe for conflict. By bisecting a highly integrated country, the division created two hostile, competing regimes that each claimed sole legitimacy over the entire peninsula. The superpowers quickly populated these zones with client leaders, setting the stage for an inevitable civil explosion. The consequences of this arbitrary line included:

• The sudden disruption of a highly integrated national economy.
• The separation of millions of families across an artificial, militarized border.
• The creation of two highly militarized client states dependent on foreign backers.

The double standard. The United States defended the 38th parallel as a sacred international border when the North crossed it in June 1950, yet dismissed it as an "imaginary line" when American forces crossed it to invade the North in October. This logical inconsistency highlights how geopolitical convenience overrode Korean national sovereignty.

4. The legacy of Japanese colonialism and collaboration fueled the internal conflict.

The Korean conflict thus inherited a Japanese-Korean enmity that broke into a decade of warfare in Manchuria in the 1930s, and in that sense is almost eighty years old—and no one can say when it will finally end.

Colonial inheritance. The bitter divisions of the Korean War were forged during the brutal Japanese colonial occupation from 1910 to 1945. The Japanese administration systematically co-opted the traditional Korean elite, creating a deep-seated class of collaborators that stood in stark opposition to the patriotic resistance.

The collaborator state. Following liberation, the U.S. Military Government in the South chose to retain and employ former Japanese collaborators, particularly in the national police and military, to combat the rising left wing. This decision deeply compromised the moral legitimacy of the early South Korean state in the eyes of many patriots. This colonial legacy resulted in:

• The re-employment of hated colonial police officers to suppress domestic dissent.
• The rise of military officers who had served in the Japanese imperial army to top ROK commands.
• A fierce, revolutionary hatred in the North toward the "quisling" regime in the South.

A war of resistance. For the North Korean leadership, the war was a direct continuation of their anti-Japanese guerrilla struggle of the 1930s. They viewed the South Korean government not as a sovereign democracy, but as an illegitimate successor state to Japanese imperialism, backed by a new Western master.

5. The war was characterized by extreme, widespread, and often suppressed civilian atrocities.

Least known to Americans is how appallingly dirty this war was, with a sordid history of civilian slaughters amid which our ostensibly democratic ally was the worst offender, contrary to the American image of the North Koreans as fiendish terrorists.

A dirty war. The Korean War was an exceptionally brutal conflict characterized by widespread, systematic massacres of civilians, political prisoners, and suspected leftists. While the West focused exclusively on Communist atrocities, the South Korean regime, often under the watchful eyes of American advisers, was responsible for the majority of the slaughters.

Suppressed slaughters. In the weeks following the outbreak of conventional war, the South Korean police and right-wing youth groups executed tens of thousands of political prisoners to prevent them from aiding the North. These massacres, such as the one at Taejon, were documented by American officers but actively covered up for decades. Key instances of this violence included:

• The execution of thousands of suspected leftists and their families in trenches and mines.
• The brutal, scorched-earth suppression of the Cheju Island peasant uprising.
• The systematic "cleaning out" of political prisoners before retreating from major cities.

The cost of silence. The United States government actively suppressed photographic and documentary evidence of these allied atrocities to maintain the moral legitimacy of the war effort. This systematic cover-up left generations of survivors in South Korea suffering in silence, unable to speak the truth of their families' deaths.

6. The American air campaign inflicted catastrophic, disproportionate destruction on North Korea.

What hardly any Americans know or remember, however, is that we carpet-bombed the North for three years with next to no concern for civilian casualties.

Annihilation from above. The U.S. Air Force waged a merciless, three-year saturation bombing campaign against North Korea that resulted in the near-total destruction of its urban areas, infrastructure, and industrial base. This campaign utilized more napalm and conventional explosives than were dropped in the entire Pacific theater during World War II.

A scorched earth. When conventional military targets ran out, American bombers targeted cities, villages, and eventually massive irrigation dams, flooding agricultural valleys and threatening millions with starvation. This air war was designed to break the enemy's morale, but instead succeeded only in leveling the country. The scale of this destruction included:

• The destruction of 75% to 100% of major North Korean cities and towns.
• The widespread use of napalm to incinerate villages and civilian populations.
• The bombing of major agricultural dams to destroy the food supply in the war's final stages.

A subterranean society. The relentless bombing forced the North Korean population to move their entire society—factories, schools, hospitals, and homes—underground. This harrowing experience forged a deeply resilient, highly militarized garrison state that remains intensely hostile to the United States to this day.

7. The conflict permanently transformed the United States into a global national security state.

The Korean War was the crisis that, in Acheson’s subsequent words, “came along and saved us”; by that he meant that it enabled the final approval of NSC 68 and passage through Congress of a quadrupling of American defense spending.

The national security state. The Korean War was the critical catalyst that transformed the United States from a demobilized, peacetime nation into a permanent, global military superpower. It provided the necessary crisis to justify the implementation of NSC 68, which called for a massive expansion of the military-industrial complex.

A permanent mobilization. Before Korea, the United States had a long tradition of rapidly demobilizing its military forces after major conflicts. The Korean War ended this tradition, establishing a permanent standing army, a vast network of foreign military bases, and a highly influential defense industry. This transformation resulted in:

• A permanent quadrupling of the American defense budget.
• The stationing of hundreds of thousands of American troops in permanent bases abroad.
• The institutionalization of a powerful, secretive national security apparatus at home.

The imperial presidency. The war also marked a significant shift in domestic political power, greatly expanding the authority of the executive branch to wage war without congressional approval. By labeling the intervention a "police action," the Truman administration set a dangerous precedent for future undeclared foreign interventions.

8. The war ended in a fragile, unresolved stalemate that persists to this day.

No peace treaty has ever been signed, and so the peninsula remains in a technical state of war.

An unresolved conflict. The armistice signed on July 27, 1953, did not end the Korean War; it merely suspended the active fighting. Because no formal peace treaty was ever negotiated, the two Koreas and the United States remain in a technical state of war, separated by the most heavily fortified border on earth.

The frozen front. The Demilitarized Zone (DMZ) is a living museum of the Cold War, a tense, volatile buffer strip where hundreds of thousands of heavily armed soldiers face each other daily. This unresolved stalemate has kept the peninsula in a state of perpetual crisis, with the threat of renewed conflict always looming. The legacy of this stalemate includes:

• The permanent stationing of tens of thousands of American troops in South Korea.
• The development of a massive, nuclear-armed garrison state in North Korea.
• A continuous cycle of border incidents, naval clashes, and rhetorical brinkmanship.

No exit strategy. The United States has remained locked in a costly, dangerous military commitment in Korea for over seven decades with no clear exit strategy. This persistent entanglement illustrates how easy it is for a superpower to enter a foreign civil conflict, and how difficult it is to ever leave.

9. True peace requires a process of honest historical reckoning and mutual reconciliation.

But today they have become commonplace knowledge in a democratized and historically aware South Korea.

The path to peace. A lasting peace on the Korean peninsula cannot be achieved through military deterrence or economic sanctions alone. It requires a painful, honest reckoning with the historical truths of the conflict, including the acknowledgment of past crimes and massacres committed by all sides.

Restorative justice. In recent years, South Korea's transition to a vibrant democracy has allowed for the creation of the Truth and Reconciliation Commission. This body has painstakingly exhumed mass graves, documented state-sponsored massacres, and offered official apologies to the victims, setting a powerful example for the rest of the world. This process of historical reckoning involves:

• Exhuming mass graves to provide forensic truth and proper burials for the dead.
• Allowing survivors and eyewitnesses to speak their truths without fear of political reprisal.
• Dismantling the official, state-sponsored lies that have justified decades of hostility.

A shared humanity. By confronting the dark chapters of their shared history, Koreans have begun the slow, difficult process of putting their ghosts to rest and rediscovering their common humanity. Only when the United States and North Korea also engage in this honest historical reckoning can the eighty years' war finally come to an end.
