We greet with mixed emotions reports that Congresswoman Elise Stefanik has her eye on the ambassadorship to the United Nations — if President Trump wins a second term. Her work spotlighting the spread of antisemitism on campus has been heroic, especially as the Biden administration has been inclined to sit on its hands. We’d vote for her in a heartbeat. Sending her to Turtle Bay, though, would be like the Yankees sending Juan Soto to the minor leagues.

There is no doubt Ms. Stefanik could, if anyone can, advance our cause in the UN. What would be the point? The United Nations’s hostility to America and Israel is so deeply woven into the warp and woof of the place that even Ms. Stefanik’s considerable abilities could prove ineffectual. It would make sense for Ms. Stefanik if her assignment was to be part of an effort of America to pull out of the United Nations altogether.
