The naval analogy is interesting. One of the six missions of a global naval presence is to protect the sea lanes of communication. Even if that means the North Koreans occasionally manage to acquire some centrifuge tubes, the global value of trade outweighs the costs.

It's tough to go to war with major trade partners.
