In my state, Oregon, we locked down when there were only a handful of cases, and not much community spread. Most spread was either in long-term care or familial. But we locked down _hard_ and had pretty good compliance. I am talking, standing in the middle of I-5 at noon compliance. Sure you'd have to keep an eye out for trucks from time to time. But still.
We set up surge capacity. Hospitals in Portland set up triage tents and cleared out other beds for a surge...... that never came. A few weeks in, the tents were taken down, the staff was laid off. We sat in our cocoon waiting for something, not sure what. Eventually the pain of being closed started to tick away, and we started reopening...
But nothing materially _changed_ between then and now. We just stopped community spread of an infection nobody really had. We've had less than 6k infections in Oregon. Now we are opening up and guess what? Cases are increasing! We didn't flatten the curve we crushed the curve. So there was no controlled spread, it was just us all feeling proud of ourselves for three months while the poor suffered.
The sneaky lie was that, in a country as big as the US, a flatten the curve strategy was never going to work at a national level. We need community level response.
We locked down Oregon over what was happening in NYC. That is akin to Northern Ireland locking down because of Moscow. That isn't an exaggeration. If anything, it is an understatement.
All of the European countries that we are saying "why can't we be more like them?" all had orders of magnitude more cases than Oregon. So if Oregon quadruples in cases over the next month we are still better off than a lot of nations.
To flatten the curve, there needs to be a damn curve to flatten. Had we waited until there was known, uncontrolled community spread and _then_ shut down, we would have a lot more political will. Now if it gets to that point after three months of being shut down, I doubt anyone will give a shit what the Governor says. Goodwill has been burned through and then some.
