Finishing up a thought of yesterday's.
Though recent North Korean rocket launches have sent projectiles in the general direction of Japan, and though Japan is the "former colonial power," I very much doubt that there is any close connection between those two facts. Why?
Because I ask myself, Where else could they have directed those missiles? Southward? Only when they're ready to resume the war paused more than 60 years ago. North? Siberia, a/k/a Russia. They wouldn't dare. West? The People's Republic of China. Again, they wouldn't dare.
They send the missiles over the open seas, even though that makes Japan nervous, because that is the only testing range they dare employ.
Mystery solved. You're welcome.
