The world has watched in horror as an American president acts not as the leader of the free world but as a quack apothecary recommending unproven “treatments.” It has seen what “America First” means in practice: don’t look to the United States for help in a genuine global crisis, because it can’t even look after itself. Once there was the United States of the Berlin airlift. Now there is the image of the USS Theodore Roosevelt crippled by the virus, reports of the administration trying to take exclusive control of a vaccine being developed in Germany, and federal intervention to stop the commercial sale of personal protective equipment to Canada. The world has been turned on its head.
