A presentation on “Update on Nuclear North Korea and a Tour around the Rest of the Nuclear World” with former LANL Director Siegfried S. Hecker of Stanford University is 7 p.m. Saturday, Jan. 27, at Church of Jesus Christ of Latter-day Saints, 1967 18th St. in Los Alamos.

The fear of a nuclear crisis in North Korea that gripped much of the United States in 2017 was followed by a ray of hope in early 2018. Hecker will provide an assessment of the North’s nuclear program today and what the future may bring.

Hecker also will provide a brief summary of his views of nuclear challenges around the globe, particularly developments in Russia, China, India, Pakistan, Iran, Central Asia and the threats from terrorist networks.
