threat and fear of the possibility of nuclear/ chemical warfare from North Korea...but in conventional ones you can still reap the seeds of the sow...with nuclear outbreak the aftermath is unthinkable...its more of a deficit to hold the grounds u struck with your warheads...nuclear winters...infections...dieseases breaking down the immune systems of the human body...Japan's watched at their backs by the U.S while China (a power house) and Soviet Union (another one) will not sit around waiting for that to happen.
anyway the mapping's rather creative in my opinion.
