Why North Korea’s Nuclear Arsenal Is a Growing Worry

In justifying the war they launched on Iran at the end of February, the US and Israel said they wanted to ensure the country wasn’t able to build nuclear weapons. North Korea, another state alienated from the West, has long had these capabilities, and has recently significantly increased its capacity to produce such arms, according to the International Atomic Energy Agency.

During the first Trump administration, the US tried to negotiate denuclearization with North Korea. But the country’s leader, Kim Jong Un, chose to retain the “nuclear shield and sword” that state media says has protected the regime from operations such as the one against Iran.
