We are back at it — negotiations over Iran’s nuclear weapons, possibly with a limited or even a comprehensive war as the other means of dealing with the Islamic Republic. Whatever happens in the coming days and weeks, these negotiations and any resulting arrangement should not give the Tehran regime a license to kill its own population or continue destabilizing the region. To negotiate with Iran on the nuclear issue alone is to repeat the mistakes of the past, granting the regime legitimacy while ignoring the regional machinery of repression and proxy warfare that sustains it.
