By choosing Mike Pompeo as his new secretary of state and John Bolton as national security adviser, U.S. President Donald Trump has formed a hawkish anti-Iran team, indicating that he is planning to bypass diplomacy, scrap the Iran nuclear deal and possibly resort to regime change or military action.

Trump's anti-Iran team is backed by its regional allies. He held meetings at the White House with Israeli Prime Minister Benjamin Netanyahu on March 5 and Saudi Crown Prince Mohammed bin Salman on March 20 to seal the cooperation. Additionally, on March 23, American, Saudi and UAE national security advisers got together in the White House to discuss how "to counter the Iranian regime's malign influence and provocative behaviour".

President Trump may have his teams in place, but it still won't be easy for him to take decisive action on Iran. Trump is expected to scrap the nuclear deal in May as a first step, however, even this won't be an easy decision for him to make. In the same month, he is planning to hold a crucial first meeting with North Korean leader Kim Jong-un, who would likely be disinclined to trust a president who has just opted out of an international accord.

He may decide to face all possible repercussions and scrap the deal anyway, but then he would be left with an even harder question: what to do with Iran after breaking the deal? His most likely option would be to try and create some form of chaos to destabilize Iran and push the Iranian establishment out of its comfort zone so the U.S. can dictate terms and get the upper hand. This could be through sending logistic and financial support to the opposition inside Iran, funding proxy "terror" attacks, meddling in elections or supporting internal protests and demonstrations.

Even though there is widespread anger in the country about lack of economic progress, the leaderless and unorganized opposition forces in Iran are unlikely to knowingly cooperate with the U.S. to topple the Iranian establishment. They know that any such move would be dealt with by Iran's security forces. Also, the memory of the 1953 coup instigated by the U.S. is still fresh in Iranians' minds so it is unlikely that the opposition would support another U.S.-backed coup or regime change.

Moreover, the strongest opposition force in Iran is already in power. Moderate President Hassan Rouhani has formed an alliance with the reformist camps, and together they are pushing for creating openings within the system through the very limited means available to them. Their mode of cooperation with the West was through the Iran nuclear deal and scrapping it would be the last straw for them.

John Bolton has in the past advocated a joint attack by Israel and the U.S. on Iran's nuclear facilities, combined with "vigorous American support for Iran's opposition, aimed at regime change in Tehran". This is a futile and dangerous solution.

Attacking Iran's nuclear installations would provoke a fierce response from Iran's Revolutionary Guard Corps (IRGC), engulfing the entire region and possibly leading to confrontation with Israel.

The idea of regime change without a viable alternative has also proved problematic in the most recent cases of Iraq and Libya. The seven-year U.S. attempt at replacing Bashar al-Assad of Syria has also failed. 

Moreover, Bolton advocates bringing to power in Iran a former "terrorist" group, Mujahedin-E Khalq Organisation (MEK), which he regards as a "viable" alternative to the Islamic Republic. 

Bolton's belief in the MEK is ill-founded. The group with a catalogue of human rights abuses has an ideology that blends Islam and Marxism and is referred to as "a cult" by some experts. Although it claims to have adopted moderate policies since 2012 when it was removed from the U.S. "terror" list, most Iranians continue to take a strong exception to its decision to fight in support of Saddam Hussein during the Iran-Iraq War in the 1980s. 

Research at Boston College shows that the U.S. tried to change other countries' governments 72 times during the Cold War and in 66 cases this was done by covert action. According to the data, most of these attempts failed, demonstrating that attempts at regime change "rarely work out as the intervening states expect". 

Moreover, 40 percent of the states that have had foreign-imposed governments have experienced civil wars within the next 10 years.

"Americans are pushing for harder policies towards Iran, and we need to strengthen our view towards the East, especially China and Russia," Alaeddin Boroujerdi, head of Iranian parliament's National Security Commission, told ISNA news agency.

President Trump's trade war with China, his unprecedented diplomatic war with Russia, combined with the hardening of his stance towards Iran can only further strengthen Iran's military and economic ties with the two eastern powers to the detriment of the West. 

With Russia and Iran both isolated, they would cooperate more on covert action in areas of particular U.S. interest such as Afghanistan and consolidate their victories in Syria. Iran would pour far more funds in support of Hezbollah, Palestinians, and the Assad regime. 

As of March 2018, the Trump administration has moved away from diplomacy towards increasing the deployment of special operations forces to 149 countries - up from 138 in 2016. 

Trump certainly appears to have all but lost the chance to create some kind of platform for direct talks with Iran. But his options for an alternative, hawkish approach also seems to be extremely limited.
