Washington( CNN) The Trump administration can claim a genuine foreign policy win, marked by deft diplomacy on two continents, following the passage of the most punitive UN sanctions ever imposed against North Korea.

But it is impossible to say whether the$ 1 billion blow will slow the most serious national security crisis facing President Donald Trump: Pyongyang’s race to top an intercontinental ballistic missile who are able to hit US soil with a nuclear warhead.

Washington and its friends will hope that the new assault on Pyongyang’s already heavily sanctioned economy will change Kim Jong Un’s computations in the building nuclear showdown.
