Do you not know that North Korea is quite mountainous, and this was one of the big reasons that the US, at the height of its powers right after WWII, owning 35% of the world GDP, was pushed back by China, the poorest country on earth with a life expectancy of 35 years, during the first Korean War? Do you think that the Americans called a truce with North Korea and China because it was winning so much that it was embarrassing? You think? The mountainous terrain of North Korea will make a nice meat-grinder for both the Americans and the North Koreans.
The North Koreans will never surrender because the last time the US was at it, it killed 20% to 30% of the North Koreans with Napalm raining down on every single city in the country, so the North Koreans expect nothing but a fight to the death for everybody, including women and children.
“Over a period of three years or so, we killed off — what — 20 percent of the population,” Air Force Gen. Curtis LeMay, head of the Strategic Air Command during the Korean War, told the Office of Air Force History in 1984. Dean Rusk, a supporter of the war and later secretary of state, said the United States bombed “everything that moved in North Korea, every brick standing on top of another.” After running low on urban targets, U.S. bombers destroyed hydroelectric and irrigation dams in the later stages of the war, flooding farmland and destroying crops.
