WASHINGTON — Iran's clerical regime governs by a simple formula: He who is the most frightening wins. "Victory by terrifying" is a trope that is present in many of Supreme Leader Ayatollah Ali Khamenei's speeches. Indeed, it is a reliable guide to his political philosophy.

This view was not invented by Khamenei, but rather is drawn from the Quran and the Shiite tradition. The Iranian Revolutionary Guard have uniforms bearing a Quranic verse that reads, "Make ready for them whatever force and strings of horses you can, to terrify thereby the enemy of God and your enemy, and others besides them that you know not; God knows them."

Furthermore, in the Shiite tradition, the strategy of the Mahdi, the Shiite messiah, will be to intimidate all his enemies upon his return to Earth.
