South Korea wins alone, they are only apparent allies. It will be a difficult war. Between allies they are also going to fight, they are going to dispute in some type of war, be it commercial or technological. Each country will be looking for its own independence and stand out.
South Korea's economy will be booming for a few years. Mourning in South Korean politics, a minister or former president dies.
Earthquake for South Korea or nearby to this country between 2023 and 2026. I have also visualized an explosion, a fire where many people will die.
