Why the Korean War Was One of the Deadliest Wars in Modern History
It’s difficult to try to keep up with developments in the latest round of saber rattling between the United States and North Korea. U.S. President Donald Trump and Korean “supreme leader” Kim Jong-un have repeatedly traded verbal barbs via Twitter and more formal avenues amid news of naval redeployments, massive live-fire artillery exercises, United Nations condemnations and rumors of troop movements by regional powers.
The United States would have an obvious and distinct advantage over North Korea in a direct military engagement. That doesn’t mean that a war wouldn’t be a grueling and costly endeavor. North Korea’s military is dilapidated and antiquated, but it’s still one of the largest militaries in the world. When the two countries clashed before, from 1950 to 1953, the conflict ended in a virtual draw along the 38th parallel.
Of course, the hundreds of thousands of soldiers China sent to save its North Korean ally played a decisive role in that outcome, but the Korean People’s Army itself put up a formidable fight against the much more powerful United States and its allies. The KPA inflicted considerable casualties in a blitzkrieg-like assault through the south and quickly seized huge swaths of territory, compelling the United States to implement a scorched-earth policy that inflicted a tremendous death toll.
On a per-capita basis, the Korean War was one of the deadliest wars in modern history, especially for the civilian population of North Korea. The scale of the devastation shocked and disgusted the American military personnel who witnessed it, including some who had fought in the most horrific battles of World War II.
World War II was by far the bloodiest war in history. Estimates of the death toll range from 60 million to more than 85 million, with some suggesting that the number is actually even higher and that 50 million civilians may have perished in China alone. Even the lower estimates would account for roughly three percent of the world’s estimated population of 2.3 billion in 1940.
These are staggering numbers, and the death rate during the Korean War was comparable to what occurred in the hardest hit countries of World War II.
Several factors contributed to the high casualty ratios. The Korean Peninsula is densely populated. Rapidly shifting front lines often left civilians trapped in combat zones. Both sides committed numerous massacres and carried out mass executions of political prisoners. Modern aircraft carried out a vast bombing campaign, dropping massive loads of napalm along with standard bombs.
In fact, by the end of the war, the United States and its allies had dropped more bombs on the Korean Peninsula, the overwhelming majority of them on North Korea, than they had in the entire Pacific Theater of World War II.
“The physical destruction and loss of life on both sides was almost beyond comprehension, but the North suffered the greater damage, due to American saturation bombing and the scorched-earth policy of the retreating U.N. forces,” historian Charles K. Armstrong wrote in an essay for the Asia-Pacific Journal.
“The U.S. Air Force estimated that North Korea’s destruction was proportionately greater than that of Japan in the Second World War, where the U.S. had turned 64 major cities to rubble and used the atomic bomb to destroy two others. American planes dropped 635,000 tons of bombs on Korea—that is, essentially on North Korea—including 32,557 tons of napalm, compared to 503,000 tons of bombs dropped in the entire Pacific theatre of World War II.”
As Armstrong explains, this resulted in almost unparalleled devastation.
“The number of Korean dead, injured or missing by war’s end approached three million, ten percent of the overall population. The majority of those killed were in the North, which had half of the population of the South; although the DPRK does not have official figures, possibly twelve to fifteen percent of the population was killed in the war, a figure close to or surpassing the proportion of Soviet citizens killed in World War II.”
