Solution of international dispute

It seems that the U.N. undersecretary general has visited North Korea this time. Of course it should have persuaded to stop nuclear development.
Also, the Secretary General of the U.N. will visit Japan and seems to talk with the Prime Minister. Naturally, the abduction issue should be discussed too.
I think that international conflicts are piled up including the problems surrounding the capital of Jerusalem this time, so the United Nations should move aggressively to mediate them.
