Denuclearizing North Korea

More than three months after the Singapore summit at which U.S. President Donald J. Trump and the North Korean leader Kim Jong-un agreed to work toward “complete denuclearization of the Korean Peninsula,” the negotiations appear to have stalled. As the first meeting ever between a sitting U.S. president and a North Korean leader, the summit was no doubt a landmark event. It was also widely hailed as a critical development to avert the risk of a nuclear confrontation. Trump went even further, declaring that there was “no longer a nuclear threat” from North Korea.
