It won't be so easy to fight. Once a war is launched, it will greatly affect the economy, politics, diplomacy and national security of the whole country, especially for South Korea, where people are rich and want a stable life, and they are very afraid of fighting. North Korea has never given up its research on nuclear weapons, so the United States and South Korea can only use both hard and soft, but when it is hard to a certain extent, South Korea will have to be soft. After all, it is very difficult to launch a missile in case it is really close, so it will not be so easy to fight, not to mention that they are all of the same nation. There are also a lot of troops assembled in Hunchun. Don't be afraid, our safe country has long considered it!
Finally, I wish you a happy life and a harmonious family!
