The allegation, true or not, could alter nuclear‑non‑proliferation negotiations and heighten strategic mistrust between the United States and China.
The video examines the Trump administration’s claim that China carried out an undeclared nuclear test in 2020, citing a low‑magnitude seismic event detected in western China’s test range.
Zeihan explains that the event registered about 2.7 on the Richter scale—comparable to a fracking tremor—and would correspond to a yield of only a few tens of tons, far below the kiloton‑scale weapons China fields. He also outlines the engineering hurdles of creating a 100‑foot underground cavity at 800‑foot depth, questioning whether Beijing possesses the requisite technical capacity.
No arms‑control specialist publicly accepts the nuclear interpretation; experts argue the data more likely reflect conventional explosives or sensor noise. Zeihan suggests the allegation may serve a political purpose, possibly to pressure China or to justify a U.S. revival of nuclear testing under the Trump administration.
If unfounded, the claim risks inflaming U.S.–China tensions and undermining confidence in the global monitoring regime, while a genuine test would signal a breach of the remaining nuclear‑test treaties, reshaping non‑proliferation strategies worldwide.
