What the saber rattlers and chest beaters refuse to understand. is that North Korea's nukes are regime insurance.
Let's try negotiating the easing of sanctions AND leaving North Korea's leaders alone for stopping the nuke program.
The hawks will scream about how bad North Korea's leaders are. There are lots of bad national leaders out there. Iran beheads Baha'i and Manichaeism believers. Saudi Arabia arrests women who drive cars. Singapore runs a rigidly controlled authoritarian state that whips criminals. And on and on.
We cannot solve every country's problems.
We have no authority to re-mold every country in our image.
