President Macron’s shocking call on French radio to “stop supplying weapons to lead the fighting in Gaza” is yet another moral failure for the country that brought us Vichy.

Mr. Macron also called for the Jewish state to stand down in Lebanon, where the Israel Defense Forces are attacking Hezbollah — and Iran.
