The USA have alerted NATO allies and Israel in mid-November (!) about coronavirus: https://www.timesofisrael.com/us-alerted-israel-nato-to-dise...
The ban on China travel came two months later. Two months of inaction that have cost a lot of lives. If it's any solace, us other NATO countries haven't been better, but at least our leaders were not as stubborn as to claim "corona was under control" until Feb. 24 or "[the Democrat's] new hoax" (Feb. 28) as Trump did.
The ones who did not waste any time and who actually do have a standing pandemic response team are Asian countries like Taiwan - Taiwan is directly adjacent to China, has a shitload of travel to China under normal circumstances, got sidelined from the WHO thanks to Chinese pressure, yet only 422 cases with 6 deaths IN TOTAL.
That's what happens when a competent government is in action: they locked down travels on end of december and put actual experts in charge.
What does Trump do, in contrast? Infection rates are nowhere near "under control", and he appoints his daughter and son-in-law on a "council to re-open America": https://www.vox.com/policy-and-politics/2020/4/14/21220755/t...
