The hard-earned good news is that Covid-19 has shown us what we need to do. We cannot let a virus catch our interconnected global community this stupidly flat-footed again. We cannot let it break those interconnections either, at least not all of them. If this pandemic teaches us anything, it is that up against a contagious disease, we are all in this together. One big early lesson was that no country can really seal off their borders anymore, or go it alone. Our society is global; our risk is global; our response and our cooperation must be global.
