We can abandon whole defense facilities in the world

In the past, Japan has a civilization who didn’t have self defense facilities (Yoshinori Yasuda, 縄文文明の環境, p. 164) and had continued for 10,000 years, the longest civilization in the world; Jomon civilization. In the current era that we share great experiences of past human history, I believe we can abandon whole defense facilities in the world. I hope Japan will lead it with the constitution, or don’t mind if an other country will do and makes Japan be ashamed.
