History shows us that seismic events have the potential to unite even politically divided Americans behind common cause. In the U.S., the COVID-19 pandemic has already taken more than seven times the number of lives as terrorists did in the 9/11 attacks, but the outpouring of solidarity Americans have shown for one another has so far not translated into more unity over government’s proper role at home or America’s proper role abroad. Indeed, the virus struck in an era of the most virulent polarization ever recorded—an unprecedented 82-percentage point divide between Republicans’ and Democrats’ average job-approval ratings of President Trump. And so far that gap appears only to be widening, while internationally, political leaders are trading recriminations rather than coordinating the procurement of medical supplies.
But the shared enemy of a future pandemic must bring about a redefinition of national security and generate long overdue increases of federal investments in domestic and global health security preparedness.
