Just to clarify the point: Iran is an occupied country. The native people are peaceful Persians who were overrun by Arab Muslims in 1979. Persians have long despised Arabs. There's no point in attacking the Iranian people -- they're already on our side. Precision bombing, used very selectively, is the way to go.
Syria already seems to be a 'middle man' for Iran.
Syria should be taken out, and let the original Iranians get their country back...
