The first, primary, main, supreme responsibility is national health authorities that got this catastrophically wrong. Even if you ignore the Chinese numbers, they ought to have been screaming bloody murder at the latest when Wuhan went under curfew and those emergency hospitals started going up in record numbers. It ought to have been obvious at this point that this is out of control and it's only a matter of time before it gets here, for any given "here."
Singapore imposed its lockdown on January 23. Any Western health authority not screaming at the political leadership to contain this NOW NOW NOW from that date on should be considered personally responsible for the hundreds of thousands or millions of deaths that will now surely follow. And the same responsibility lies on the politicians who ought to have been able to see they were horribly wrong at the latest a few weeks later. They ought to have been ramping up production of test kits, test vehicles, protective gear, ventilators, setting up monitoring stations at ports, airports, and public transport, and, yes, restricting travel, not just from known hotspots but pretty much everywhere. Yet the only thing that anyone did was Trump slapping a travel ban on China and declaring the problem solved - and he was the only one who did even that much.
