Fauci also stated models are only as good as the assumptions made to calculate them. The 100-240k model assumes more spikes like NYC in other large metros. If mitigation is working as he hopes he feels the number can be much lower, probably closer to the 60k bad flu season. All depends on general public doing their part with distancing, IMO.
Very regrettably, the US and UK refuse to learn lessons from Asian countries, particularly S Korea, where there is no lockdown but everyone wears a mask, testing is widespread and available to anyone, re-purposed drugs are used and deaths have dropped to a relatively small trickle.
