First, to the extent that the United States is engaged in a conflict of propaganda and soft power with the regime in Beijing, there’s a pretty big difference between a world where the Chinese regime can say, We weren’t responsible for Covid but we crushed the virus and the West did not, because we’re strong and they’re decadent, and a world where this was basically their Chernobyl except their incompetence and cover-up sickened not just one of their own cities but also the entire globe. The latter scenario would also open a debate about how the United States should try to enforce international scientific research safeguards, or how we should operate in a world where they can’t be reasonably enforced. Perhaps that debate would ultimately tilt away from China hawks, as David Frum argues in The Atlantic, because the lesson of a lab leak would be that we actually need “more binding of China to the international order, more cross-border health and safety standards, more American scientists in Chinese labs, and concomitantly, more Chinese scientists in American labs.” Or perhaps instead you would have an attempted scientific and academic embargo, an end to the kind of funding that flowed to the Wuhan Institute of Virology from the U.S.A.I.D., an attempt to manage risk with harder borders, stricter travel restrictions, de-globalization. Either way, this debate would also affect science policy at home, opening arguments the likes of which we haven’t seen since the era of Chernobyl and Three Mile Island about the risks of scientific hubris and cutting-edge research.
