I don't understand, every bad news about North Korea, USDJPY goes down, but if the worst happen, they are right next to NK, but EUA is big and on the other side of the planet, what's
the logical reason behind that, shouldn't USDJPY go up instead?
I am not so Profi but what I learned from live market in the past years, Technical analysis is more important and more effective than other things, USDJPY was in clear down trend on H1 and H4.
I prefer to wait at major Support for buy back USDJPY (^̮^)

The answer top this question is very simple:
Because it can.
If it's possible, it's inevitable.
