America’s allies in the Middle East are preparing for war, thanks in part to the growing danger they face from an Islamist Iran emboldened by the new Biden-Harris administration. They are right to do so and their warnings should prompt an urgent course-correction by the U.S. government.

The latest such alarm was sounded on Sunday by 2200 former Israeli military, intelligence and law enforcement leaders. They wrote in an open letter: "The Iranian regime explicitly and publicly seeks the destruction of our country and the toppling of governments of the Arab countries with whom we have made peace. Preventing Iran from obtaining the capability to build deliverable nuclear weapons and confronting the regime's malign activities are essential to preventing catastrophe."
