How is lab safety “not actionable”? Is it some special field of science where all improvements and progress has stopped? I don’t understand your point.

Haven’t more people died from SARS-Cov-2 than nuclear weapons, why we can’t have international conventions and inspections on dangerous virological research?

It's not actionable for the US to force China to do something, sure. China doesn't want to suffer through another global pandemic either, so it would be useful to them to know if they need to improve lab safety standards. In fact, that information would be useful and actionable for all countries that have viral research labs.

There are plenty of actions beyond military options like economic, political, and legal. China could be isolated financially with trade embargos for example. US treasuries and other nations instruments that China owns could be seized and extinguished. Bank accounts can be seized. There are many actions that could be taken if countries really desired. However, the alluring call of cheap manufacturing and a large population to market goods toward clouds most countries from taking any actions.
