New satellite photos show that Kim Jong Un is continuing to develop his nuclear weapons program, and U.S. intelligence sources say they believe North Korea has increased its production of nuclear fuel at multiple sites. This wasn’t supposed to happen after the Donald Trump-Kim summit last month in Singapore.
According to an analysis by experts at the Stimson Center in Washington, North Korea has improved the cooling system of its plutonium-producing reactor at Yongbyon. Activity also continues at a nearby building where plutonium is extracted from spent fuel, and staining on the roof of another building suggests the North is enriching weapons-grade uranium using centrifuges. U.S. intelligence sources essentially confirmed this news by telling news agencies last week that the North has been increasing its production of enriched uranium for nuclear weapons.
After the June 12 summit with Kim, President Trump said that he trusts the young dictator and expects him to start fulfilling his promise to denuclearize immediately. “There is no longer a Nuclear Threat from North Korea,” Mr. Trump tweeted the next day.
