If, early in the spring, the U.S. had mobilized its ample resources and expertise in a coherent national effort to prepare for the virus, things might have turned out differently. If, in midsummer, the country had doubled down on the measures (masks, social-distancing rules, restricted indoor activities and public gatherings) that seemed to be working, instead of prematurely declaring victory, things might have turned out differently. The tragedy is that if science and common sense solutions were united in a national, coordinated response, the U.S. could have avoided many thousands of more deaths this summer.
