I very much disliked what Ron Paul said on Iranian foreign policy. To support his opposition on the nuclear sanctions on Iran, he argues that the Soviets had a very large amount of nukes while being the greatest threat to America in history, but he fails to realize that they were a conventional threat and had many reasons not to nuke America or Europe, like getting their nation retaliated against. The Iranians (or North Korea and other aggressive small countries) don't have much to lose in that sense, so whats to stop Iran from using a nuclear weapon on America or Israel just for the sake of Islamic extremism jihad? I really do hope that Dr. Paul comes to grasp that war isn't conventional when fighting insurgents anymore (not that I support the Iraqi war).
This article is biased toward Paul but provides oversight of what he said:
