A few minutes ago, I heard, on the news, three proposals as to how to deal with North Korea, short of a full-fledged war.
In ascending order of aggression, they are as follows:
(1) Announce that any other country may have economic dealings--any economic dealings--with North Korea, or with the United States; but that it is quite impossible to deal with both--and enforce that, stringently.
This, or course, would doubtless entail our cutting all economic ties with China--which would leave some bureaucrats almost apoplectic--but it would certainly be okay with me.
(2) Shoot down any tested North Korean missile during its ascent stage.
(3) Put increased pressure upon China to rein in its client state, by announcing that we intend to sell nuclear missiles to Japan--China's arch-enemy--unless China stops the DPRK in its tracks. And truly mean it.
Personally, I would be fine with any of these...
