President Trump is not usually known for restraint, but his brief speech to the nation Wednesday morning showed tough-minded restraint of just the right sort. The language was sober without being the slightest bit weak, and the substance he announced was firm but measured.

No matter what people think of Trump personally, the path he outlined merits support, and his usual critics should respect the presidency enough to make clear to the world that, for now, the United States speaks with one voice.
