What to do about North Korea?

[Anomalocaris]

Pressure China into actually doing something about them.

Unilateral action will just draw China into the conflict.

So long as the US remains stronger than china in the western pacific, the only thing thing that will convince china to rein in North Korea is to offer to give up American support for Taiwan or cede South China Sea to china. Since that is impossible even for trump, there can be no solution to the North Korea conundrum within the current balance of power between the US and china.

There are two ways for North Korean problem to be resolved, short of an unexpected implosion of North Korea from within:

1. America implodes, and china pushes the frontier of American influence out to roughly Hawaii, and therefore has no more need of North Korea.

2. China implodes and no longer has the ability to protect North Korea.
