North Korea test-launched on Friday its first ballistic missile potentially capable of hitting America’s East Coast. It thereby proved the failure of 25 years of U.S. nonproliferation policy. A single-minded rogue state can pocket diplomatic concessions and withstand sustained economic sanctions to build deliverable nuclear weapons. It is past time for Washington to bury this ineffective “carrots and sticks” approach.
America’s policy makers, especially those who still support the 2015 Iran nuclear deal, should take careful note. If Tehran’s long collusion with Pyongyang on ballistic missiles is even partly mirrored in the nuclear field, the Iranian threat is nearly as imminent as North Korea’s. Whatever the extent of their collaboration thus far, Iran could undoubtedly use its now-unfrozen assets and cash from oil-investment deals to buy nuclear hardware from North Korea, one of the world’s poorest nations.
One lesson from Pyongyang’s steady nuclear ascent is to avoid making the same mistake with other proliferators, who are carefully studying its successes.
