I don’t want to get into an extended debate on this, not only because it’s a separate issue from the topic of this thread, but because I don’t read Farsi, and hence can’t read the speeches and documents for myself to verify what was said, and hence cannot be absolutely sure of my ground.
However, people like Juan Cole and others, who are fluent in Farsi, say that the alleged calls for extermination of Jews, which is the translation you get from sites like World Nut Daily, are better translated as calls for the expulsion of Zionists, which may be politically unacceptable, but is not morally reprehensible. Similarly, the threat to “wipe Israel off the map” is just that, a call to redraw borders and end Israeli rule of what they consider Palestinian land, and not a call for genocide. 1500 years of history suggests that Muslims would have no objection to allowing Jews to live there under a majority Palestinian government. And there have been several 21st century overtures from Muslim countries, including Iran, suggesting that they would accept an Israel confined to the original UN borders.
All of that aside, I repeat, what is your goal? Is it to try to make Iran more moderate, or is it to punish them forever for bombastic speeches of the past?
Because if we don’t want perpetual war, we have to start somewhere. And the fact is that there actually is a country that didn’t just talk about exterminating Jews, it carried it out. And it wasn’t Muslim, it was Christian. And it wasn’t in the Middle Ages, it was within the memory of hundreds of millions of people alive today. And we didn’t punish it forever; we gave it extraordinary foreign aid, including an unprecedented airlift, beginning the same year that we discovered the full extent of its genocidal programs, including horrific death camps.
But again, if your goal is not a more moderate Iran, but perpetual war, then carry on.
