JAPAN, CHINA AND NORTH KOREA

I believe there is a solution to the North Korean issue.

Have Japan raise and army of a couple million, whose purpose would be invasion, give them a couple dozen nuclear missiles under their control, a couple  of nuclear submarines with which to patrol the ocean between China, North Korea and Japan.

China would mess their pants.  They fear no one like they do the Japanese who hate China.

China would then place sanctions and restrictions on the North Korean Idiot Child Young In, like have never been seen.
