Foreign policy
Rouhani's foreign policy has been contained by the conservatism of Iranian Principlists, who fear change, while also realizing it is necessary. Furthermore, Iran's foreign policy, which was deadlocked by the efforts of Mahmoud Ahmadinejad, needs new predecessor by cautious and decisive efforts of Rouhani. The main task of Rouhani is only to develop dialogues between Iran and Political rivals including P5+1. This course can help lift sanctions that damaged the Iranian economy.
In March 2015, Rouhani sent a letter to President Obama and the heads of the other five countries negotiating with Iran, explaining Iran's stance. He announced it on his Twitter account. The US National Security Council confirmed that the letter had been passed on to the U.S. negotiating team, but its contents were not released. Rouhani also spoke by phone with the leaders of all the nations involved in the negotiations, except for the United States.
Rouhani met with British Prime Minister David Cameron, marking the first time since the 1979 Islamic revolution that the leaders of Iran and the United Kingdom have met. On 20 February 2014 the Iranian Embassy in London was restored and the two countries agreed to restart diplomatic relations.
On 23 August 2015 the embassy was officially reopened.
Rouhani's visit to New York City in September 2013 was hailed as major progress in Iran's relations with the United States. He previously said that his government is ready to hold talks with the United States after thirty-two years. Rouhani denied reports that during his trip he had refused a meeting with U.S. President Barack Obama, and felt more time was needed to coordinate such a meeting. On 27 September 2013, a day after the two countries foreign ministers met during the P5+1 and Iran talks, Rouhani had a phone call with President Obama that marked two countries' highest political exchange since 1979. However, due to this phone call Rouhani was protested by conservatives who chanted "death to America" when he returned to Tehran.
In February 2019, Rouhani condemned the United States for trying to topple Iran's ally, Venezuelan President Nicolás Maduro.
On 3 January 2020, the second most powerful person in Iran, Qasem Soleimani, was killed by the United States, which considerably heightened the existing tensions between the two countries. Rouhani said that Iran "will take revenge".
After Joe Biden won the US presidential election in November 2020 against Donald Trump, Rouhani stated that it was an opportunity for Biden's administration to "compensate for previous mistakes".
It is generally assumed that he will follow the ruling establishment in completely supporting Bashar al-Assad, Syria's contentious president, in the Syrian Civil War, as well as "strengthening the Shia Crescent" that runs from southern Lebanon, through Syria, Iraq and into Iran. In his first press conference after winning the presidential election, Rouhani said that "the ultimate responsibility to resolve the Syrian civil war should be in the hands of the Syrian people."
Rouhani has termed Iran–Iraq relations "brotherly" and signed several agreements with Iraq. Right after the Northern Iraq offensive, Iran was the first country to send support for Iraq and is a "key player" in Military intervention against the ISIL.
On Iran's relationship to Saudi Arabia, Rouhani wrote that during the Khatami administration, he, as the secretary-general of the National Security Council at that time, reached "a comprehensive and strategic agreement" with the Saudis, but that this agreement was not upheld during the Ahmadinejad government. Specifically, while discussing the episode, he stated:
there was a consensus [during Khatami's administration] that we should have good relations with Saudi Arabia. No one within the nezaam [regime] was opposed to it. I went to Saudi Arabia for the first time in 1998. At that time Saudi Arabia had accused us of involvement in the Khobar Towers bombing. I went to Saudi Arabia as the secretary-general of the SNSC. From their side, [Minister of Interior] Nayef bin Abdulaziz took part in the negotiations. The negotiations began at 10 p.m. and lasted until 5 a.m. the next morning. We finally agreed on a security agreement. I returned to Saudi Arabia in [early] 2005, and had extensive discussions about the region, mutual problems between us, and the nuclear issue. We agreed with Nayef to form four committees. They were supposed to convene every few months and pursue the issues. After I left [the post of] secretary-general, none of the committees were formed and there were no meetings.
Rouhani has criticized Saudi Arabian-led military intervention in Yemen, saying: "Don't bomb children, elderly men and women in Yemen. Attacking the oppressed will bring disgrace."
Rouhani has described Israel as "an occupier and usurper government" that "does injustice to the people of the region, and has brought instability to the region, with its warmongering policies", and a "cancerous tumor established by Western countries to advance their interests in the Middle East."
When asked in an interview with CNN to clarify his opinion about the Holocaust, Rouhani replied: "... in general, I can tell you that any crime that happens in history against humanity, including the crime the Nazis created towards the Jews as well as non-Jews is reprehensible and condemnable. Whatever criminality they committed against the Jews, we condemn". The live translation of his statements included explicit mention of the Holocaust, leading to media reports that he had acknowledged its existence, in contrast to the persistent denial of his predecessor. However, Iranian state media contradicted this, accusing CNN of deliberate mistranslation. Independent translations, including one by the Wall Street Journal, supported the position that Rouhani had not explicitly accepted the Holocaust's existence.
Rouhani termed the peace agreement between Israel and the United Arab Emirates a "huge mistake" and warned the UAE against permitting Israel to have a secure presence in the Persian Gulf.
