Only half a decade after the WW2 armistice, we got involved in the Korean War. Before that war started, we turned a blind eye to and even directly assisted South Korea’s Syngman Rhee’s genocidal massacres via execution of 800,000 “Communists” from 1945 until the start of the Korean War. These were actually leftwing guerrillas and their civilian supporters waging a legitimate war against Rhee’s repression.
The guerrilla was set off by the massacres of peaceful civilian protestors on Jeju Island in 1947. Outraged, the islanders took up arms. Rhee, with close US support, waged a brutal counterinsurgency, razing most of the capital city, killing 30,000 people, mostly civilians, and forcing almost the entire rest of the population to flee the island in terror.
During the Korean War, the US committed the most unspeakable crimes against humanity, including using chemical and biological weapons against North Korea, similar to what Japan had done to China 10-15 years before. In fact, we got the idea for this directly form Japanese war criminals, most of whom were immediately hired by the Pentagon and intelligence agencies after the war, in part for their knowledge of WMD’s.
Even the bombing campaign against North Korea was probably one of the most criminal acts of the 20th Century. A general bragged that every human being walking openly and any standing building in Korea was a target to be destroyed or killed. General MacArthur (I always hated him) demanded and almost received permission to drop 40 atom bombs on China after the Chinese entered the war.
Pyongyang was burned to the ground with incendiary weapons like napalm similar to the firebombing of Tokyo in 1945 in which we murdered 100,000 Japanese civilians with firebombs in only a few days. Most of the houses were actually made of a form of paper, so the firestorms caused by the firebombs raged wildly through the city.
We actually killed 3 million North Koreans in that war, which was 1
If you want to know why North Koreans hate and especially fear us so much, there’s your Goddamn reason. General Mattis was terribly worried that he would have to implement a war plan involving dropping 40 nuclear bombs on North Korea in case of a North Korean attack, so you can see that if we fight another war against North Korea, we will just as vicious and evil as before, if not much worse. This why you see the near-fanatical hatred and fear of the US, along with the frenzied mass buildup of one of the impressively militarized North Korean army, the 4th largest military in the world.
