In July 2006, the Democratic People's Republic of Korea (North Korea) conducted seven consecutive missile launch tests. It goes without saying that I was very angry when I heard the news. At that time, I was also worried about whether this would start a nuclear war. Fortunately, as of April 2007, the worst has been avoided, but I feel that the situation remains unpredictable.
There is no doubt that if the situation worsens, it will lead to the collapse of the earth, and I strongly feel that we must avoid acts that lead to the destruction of the earth in a broad sense, regardless of North Korea.
By the way, a few days after writing this work, North Korea conducted an underground nuclear test for the first time.
