The Republicans think Don Trump deserves the Nobel Prize for bringing North Korea to heel. Kim Jong Un did, after all, promise to close the country's nuclear test site. Way to go, Donnie.
Only maybe it wasn't really Trump's doing. Maybe King Jong Un had other reasons to shut it down. The South China Morning Post offers a more plausible explanation.
North Korea’s mountain nuclear test site has collapsed, putting China and other nearby nations at unprecedented risk of radioactive exposure, two separate groups of Chinese scientists studying the issue have confirmed.
One group of researchers found that the most recent blast tore open a hole in the mountain, which then collapsed upon itself. A second group concluded that the breakdown created a “chimney” that could allow radioactive fallout from the blast zone below to rise into the air.
