From a recent RAND poll of Iranians:
Like all surveys, take with a grain of salt. It's interesting that the higher the education level, the least in favor Iranians are of developing nuclear weapons. Perhaps it's because they understand better that, officially, Iran is not trying to develop weapons but secure its right (according to the NPT) to enrichment. Of course at the popular level on all sides of this conflict it's become about nukes, even when the real matter at hand is enrichment and inspections. I also don't quite understand why the pollster is making guesses about the willingness of Iranians to criticize the state of the economy (reported by some to be quite dire) and not take them at their word on this issue when they do on the other issues.
