Good News Network reports a remarkable milestone that received little fanfare: January 14th marked the longest period in history without a nuclear weapon being detonated since the atomic age began with the Trinity test in 1945.
The last nuclear test was conducted by North Korea in September 2017. This extended pause reflects the strength of international norms against nuclear testing and the success of the Comprehensive Nuclear-Test-Ban Treaty.
