I don't think that's the case. I think most of the people in Iran recognize that it is the Iranian government's own failed economic policies that have caused most of the hardship in terms of unemployment and the downturn in the Iranian economy, as has the oil situation.
I think sanctions have not yet reached that threshold where they can be blamed for creating the economic difficulties Iran is facing. They're insufficient for that. U.S. sanctions have been around for so long now that, as I said, they've been digested. President Clinton reinstated a full range of sanctions in 1995. Since then, Iran has substituted in just about every respect for any way in which lack of American products and services has caused them any hardship. Unfortunately, they've also developed ways of circumventing the American sanctions. Hewlett Packard, for example, is still the favourite printer to be found in Iran. It's acquired through Dubai. Many other U.S. products still find their way to Iran through third-country intermediaries.
Again, I don't think the U.S. sanctions have had that impact.
