Summary of Findings


1. Declining Enthusiasm for Nuclear Deal 
While the nuclear deal is still supported by a majority, since a year ago this number has diminished, with the number approving strongly dropping by half. A contributing factor may be that, contrary to expectations, a large majority does not perceive improvements in economic conditions as a result of the nuclear deal. Continuing majority support for the deal is buoyed by some optimism that the deal will improve people’s living conditions eventually. 

Declining approval of the deal may also be related to increasing awareness of the concessions that Iran made as part of the deal. This may yet worsen, as a majority continues to believe incorrectly that the deal does not allow inspection of military sites under any conditions.

The salience of the nuclear deal is linked to persisting, overwhelming support for Iran’s nuclear program, coupled with the belief that developing nuclear weapons is contrary to Islam, and that the Middle East should be free of nuclear weapons. 

2. US Seen as not Fulfilling Commitments Under Nuclear Deal 
In general, a growing majority of Iranians are not confident that the US will live up to its obligations under the nuclear agreement.  Large majorities believe that, while the United States has lifted the sanctions it agreed to lift in the JCPOA, it is finding other ways to keep the negative effects of those sanctions and, contrary to the terms of the agreement, is trying to prevent other countries from normalizing their trade and economic relations with Iran. Three in four believe that the United States is also trying to impede legitimate nuclear cooperation between Iran and other countries. Two thirds say Iran’s relations with the United States have not improved as a result of the nuclear deal.

3. Other P5+1 Countries Viewed More Favorably Re: Nuclear Deal 
Six in ten believe that other P5+1 countries, in contrast to the US, will fulfill their obligations under the nuclear deal. Also in contrast to the US, a large majority thinks Iran’s relations with European countries have already improved as a result of the nuclear deal—though this has slipped lately. 



4. Ahmadinejad Gaining on Rouhani 
While Rouhani is still favored for the 2017 presidential election, his support has dropped below half. Former president Mahmoud Ahmadinejad in particular has made gains, narrowing the gap with Rouhani to eight points.  Large majorities still say they have a favorable view of Rouhani and approve of his efforts to improve security and international relations.  But his performance on the economy gets mixed marks, with six in ten saying the economy is bad and eight in ten saying it is not improving. Three in four say he has been unsuccessful in reducing unemployment.  

5. Support for Rouhani Increasing Civil Liberties in Iran 
Two in three Iranians believe that it is important for President Rouhani to seek to increase civil liberties in Iran. However, only a small minority complains that Iranians have too little freedom. While only about a third thinks that civil liberties in Iran have increased during Rouhani’s presidency, a majority voice optimism that civil liberties will increase in the coming two years. 


6. Support Declining for Cooperation with US but Not International Community on ISIS 
While at the time of the nuclear deal six in ten favored cooperation with the United States against ISIS in Iraq, now a majority is opposed. But eight in ten Iranians still approve of Iran participating in the international negotiations over the future of Syria. Two in three also think Iran should use its influence with key players in Syria to help secure a lasting ceasefire between Assad and the Syrian opposition not affiliated with terrorist groups.

7. Support for Increasing Iran’s Role in the Region and Against ISIS 
Large majorities think Iran should increase the role it plays in the region and augment its support for groups that are fighting ISIS, which is viewed negatively by a near unanimous majority. Two thirds support sending Iranian military personnel to Syria. However, only half approve of stepping up support for the Assad government. Eight in ten approve of Iran collaborating with Russia to help the government of Bashar Assad counter ISIS.


8. Views of the United States Remain Negative 
Views of the United States, especially the US government, continue to be quite negative, and less than a third expect the relationship between Iran and the United States to improve over the next three years. Majorities continue to support a variety of people-to-people exchanges and confidence-building measures, but these numbers are declining.  A bare majority continues to have a positive view of the American people. 

9. Views of Other Countries and Organizations 
Iranians view their country’s allies, notably Iraq, Syria, Lebanon, and Hezbollah, favorably, while already negative views of Saudi Arabia and Turkey have worsened. Views of Russia and China are generally favorable. 

Western countries, with the exception of Germany, are viewed unfavorably, with Britain and the US viewed negatively by large majorities in Iran. Nonetheless, a majority thinks that it is better for Iran to increase its economic engagement with Western countries. A majority thinks that it possible for Islam and the West to find common ground.



10. Source of News and Information 

Iranians obtain their news and information from a variety of sources. Two in three Iranians watch domestic television channels every day to become informed about the news. An increasing proportion of Iran’s population goes regularly to the internet for news. About a third of Iranians continue to follow the news programs of VOA and BBC.
