WHO was inspired by the US around a century ago to facilitate a cooperative global response to things like smallpox, polio etc. which has been highly successful. There is plenty of blame to go around as far as the response to covid - 19 and if there is a problem with WHO , address it . But this should be done constructively . A decision to abandon an organization designed to prevent pandemics in order to prevent pandemics makes no sense, and It is hard to see how this will help anyone but Trump , who seems to be trying to make it look like everyone else including WHO and CHINA have responsibility while he shares none himself .
