When a new coronavirus emerged in China and began spreading around the world, including in the United States, President Donald Trump's many critics in the American foreign-policy establishment were quick to identify him as part of the problem. Trump had campaigned on an "America first" foreign policy, which after his victory was enshrined in the official National Security Strategy that his administration published in 2017. At the time, I served in the administration and orchestrated the writing of that document. In the years since, Trump has been criticized for supposedly overturning the post–World War II order and rejecting the role the United States has long played in the world. Amid a global pandemic, he's being accused—on this site and elsewhere—of alienating allies, undercutting multinational cooperation, and causing America to fight the coronavirus alone.
