Japan must know the real situation about North Korea.

Almost Japanese people comprehend that U.S.A. changed the policy about North Korea.
This isn't right way.
Almost Japanese people think,
"U.S.A. said to North Korea DIALOGUE."
Japanese people think,
"U.S.A. speak so softly against North Korea."
This is 10% O.K.
But..........
Let me say the real situation.
U.S.A. said to North Korea,
"Check Mate"
Hey Japanese people,
Do you know That?
