If the virus turns out much less deadly than we originally thought, we actually overreacted.
If the economic and social fallout from the reaction to the virus causes more pain, suffering and death than the virus itself, we actually overreacted.
If your goal is to eliminate the virus, we acted way too late. Worth noting that eliminating a virus with asymptomatic spreaders is quite difficult.
If your goal is to flatten the curve, we have been successful.
At least 95% of the blame belongs to China. If you want to say Trump is responsible for the other 5%, fine whatever, but I'd say the CDC (failed tests), WHO (China chronies), a whole bunch of governors and even Fauci made some mistakes. Hell, even you and I are a portion to blame just for being human. See, it's your fault Jim!
