Satellite Launch is a Japan and Korea Project
So, they don’t hate each other entirely. The rocket got launched by Japan, and now Korea has a strong satellite in the sky that can monitor their Northern Korean neighbors and just about anywhere in the world. It’s the first commercial space launch for Japan which means many more will come. Just because they can, should they? Eventually, when it gets into bad hands, our local space will be an amalgam of hell. (VOA -Space Japan and Korea)
