What Trump did not say is the problem, argues David Frum in *The Atlantic*:
He offered no guidance or policy on how to prevent the spread of the disease inside the United States. Should your town cancel its St. Patrick’s Day parade? What about theatrical productions and sporting events? Classes at schools and colleges? Nothing.
He offered no explanation of what went wrong with the U.S. testing system, nor any assurance of when testing would become more widely available. His own previous promises of testing for anyone who needs it have been exploded as false. So what is true? Nothing.
And on the one thing he did say?
There was one something in the speech: a ban on travel from Europe, but not the United Kingdom. It’s a classic Trump formulation. It seeks to protect America by erecting a wall against the world, without thinking very hard how or whether the wall can work. The disease is already here. The numbers only look low because of our prior failure to provide adequate testing.
