I understood that from the article, but I stand by my position. That is not the way to pressure NK.
It is if it works better than nuclear blackmail or war which those banks are facilitating. That makes them an enemy of the USA.
What do you think is a more effective way to pressure North Korea, then..?
This is EXACTLY the way to pressure NK, through their predominate supporter in the region. These are Chinese state-run banks, and with their economy teetering on the brink, a major monetary disruption would have a detrimental effect on their country. Another way to pressure NK (via China) would be to provide Japan and South Korea with tactical nukes...
