The terrorist Iranian regime's unprecedented recent attack on Israel, which included 185 drones, 36 cruise missiles and 110 surface-to-surface missiles, is an unambiguous casus belli -- an act of war -- under international law. Of course, Iranian proxies spread across the Middle East, such as Lebanon-based Hezbollah, Gaza-based Palestinian Islamic Jihad, and the Yemen-based Houthis, have committed countless previous acts of war against Israel. But last weekend was something different entirely: For the very first time since fanatical Islamists overthrew Shah Mohammad Reza Pahlavi and took power in 1979, Iran launched such attacks directly from its own soil.
