As neoconservatives took over the Republican Party, GOP officials increasingly have acted as if Washington's consistent failure to reorder the globe to their liking reflects a lack of effort. Unfortunately, President Donald Trump appears to be basing his foreign policy on the same principle. If only he blusters loudly enough, foreign nations will fall into line.

His appointees appear to be adopting the same attitude. For instance, in his testimony before the Senate Foreign Relations Committee, Secretary of State Rex Tillerson displayed a dangerous mix of ignorance and arrogance in assuming that the United States can force Beijing to act as the administration wishes regarding North Korea.

No one wants a nuclear North Korea. But there is no easy way to stop Pyongyang.
