The week coming is the middle of August when North Korean Leader Kim has said that he will give the order to launch four missiles toward Guam (American territory).  The missiles will fly over Japan and it's said that they will try to shoot them down.
I believe that the objective is not only to test anti-missile defences sited in Japan and Guam but also to test the targeting of the NK missiles.  Pres. Trump has indicated what the consequences will be and I don't believe that he's bluffing.
