After New York’s West Side terrorist attack on Halloween, President Trump noted that the killer had entered through the diversity-visa lottery and that this was a bad policy.

While I don’t think there’s much of a causal connection between this visa program and terrorism, it is a dumb policy. More than 6.5 billion people live outside the U.S. A huge portion of them would love to live in the U.S., because the U.S. is the greatest country in the world. We can’t let them all in, but shouldn’t we work to get the best and the brightest?
