British and US intelligence were pivotal in helping the Iranian military overthrow Iran’s prime minister, Mohammad Mossadeq, in 1953.
This intervention, or meddling, as it was seen in the country, brought back to power the unpopular western-leaning monarchy of Shah Mohammad Reza Pahlavi, who was heavily dependent on US support for his power.
At the heart of this support was the promise of access to the country’s natural resources, particularly oil.
But, this alliance would soon be disrupted.

In 1979 the ground starts shifting across the country with a wave of civil unrest and popular protest.

This uprising would see the grand ayatollah, Ruhollah Khomeini, return from years of exile – his platform and power fuelled by vehement opposition to what he considered a servile pro-western monarchy.
Taking power with an iron grip, the new Supreme Leader would transform the country into a radical Islamic theocracy.
But this takeover would not end at Iran’s borders.
At the heart of the transformation, there was a desire to spread the revolution to neighbouring countries – a project that continues to this day.
In 1985 the emerging militant group Hezbollah pledged its allegiance to Khomeini – that relationship has gone from strength to strength.
And thanks to Iran’s patronage Hezbollah is now the most powerful militant group in the world, often described as a state within a state in Lebanon.

How does Iran influence the Middle East?
The spread of Iranian influence would grow exponentially over the next four decades, increasingly setting the country on a collision course with the United States and its allies.
The first big clash came quickly.
It arose after 52 American diplomats and citizens were taken hostage at the US embassy by radical Iranian students.
They were held for 444 days from 4 November 1979 until their release in 1981.
The US saw this as a serious breach of international law, but in Iran it was viewed as a blow against excessive US influence and meddling in the country.
It also burnished the credentials of the new regime, who opposed normalising relations with western countries – particularly America, which was labelled the Great Satan by the ayatollahs in their increasingly fiery speeches about foreign policy.

Operation Eagle Claw – a disastrous US attempt to free the hostages – saw a helicopter crash into a transport aircraft, causing a fire that killed eight servicemen.
During this time the US had cut diplomatic ties with Iran and banned most trade – things were not looking great.
In 1980 Iraq invaded Iran – the countries had been massive rivals but were now at war. The United States lent its hefty support to Iraq led by Saddam Hussein. The fighting, which dragged on until 1988, saw huge casualties on both sides but it is estimated as many as one million Iranians died in the conflict.
Relations with the US would remain bad. The Beirut Barracks bombing, Operation Praying Mantis, the Iran-Contra Affair and sanctions were the punctuation marks for two countries ideologically opposed, that were seemingly always at, or close to conflict.
That was until 1998 when there appeared to be glimmers of hope that relations were improving. Secretary of state Madeleine Albright met with Iran’s deputy foreign minister – it was the highest level contact since the revolution but it would not last.

A few years later in 2002 and in a seminal speech President George Bush was labelling Iran as part of the “axis of evil” – its bedfellows Iraq and North Korea.
US officials would also claim Iran was operating a clandestine nuclear programme with the intent of building a bomb.
These were the years after 9/11.
Attempts to reach diplomatic understandings since then have mostly ended in failure.
President Barack Obama tried to use the carrot of sanctions relief to tame Iran’s nuclear program.
The agreement would eventually emerge as the Joint Comprehensive Plan of Action (JCPOA).

It was hoped that the deal would steer Iran away from the big bomb, or at the very least slow progress; but many Republicans viewed it with suspicion arguing that it – along with the lifting of sanctions – gave the Iranians more power to spread their pernicious influence across the region.
Enter stage Donald Trump. Exit stage deal. The one-time – but perhaps soon to be two – US president ripped up the agreement when he withdrew America from the JCPOA.
Iran and America were soon back in a spiral of escalation. President Trump would later designate the Iranian Revolutionary Guard Corps (IRGC) a terror organisation.
Perhaps, the most significant event that underlines how broken the relationship is and how far apart the two countries have become came in the form of a US drone strike on 3 January 2020.

Qasem Soleimani, the commander of the IRGC Quds force and one of the most powerful men in Iran – and by extension the region – was killed in the attack in Baghdad.
The American action sent shockwaves through the Middle East and Iran vowed revenge.
The regime also stated it would no longer restrict its nuclear program.
All of this forms the backdrop to current events. It is hard to see in the present climate how things can improve.
In fact, with the war raging in Gaza and Iranian-backed militias across the region taking pot shots at US forces, things look set to get even worse.
Israel had “no other choice” but to attack Iran because it was proceeding “dramatically” towards a nuclear bomb, Israeli President Isaac Herzog has claimed.
He also suggested the Israeli war cabinet was discussing Iran’s Supreme Leader, Ayatollah Ali Khamenei, amid reports that President Donald Trump vetoed a plan to kill him.
It comes as Israel and Iran continue to fire missiles at each other after Israel launched an unprecedented strike on Iran’s nuclear and military capabilities.
Tehran has long denied that its nuclear program has been attempting to obtain a nuclear weapon.

Sky’s Yalda Hakim interrupted by air raid sirens
Mr Herzog was asked why Israel attacked Iran when it did.
“When you take such decisions of historic magnitude and proportions, you have to analyse all facets and all facts,” he replied.
“The truth of the matter is there was no other choice.”

He claimed Iran was proceeding “dramatically” towards the bomb, both in terms of the enrichment of uranium and, “clandestinely”, the armament part of the process.
“I’ve always been very crystal clear with regards to a nuclear capability of our enemies – it has to be removed at once.”
Mr Herzog added: “We have to remove the Iranian nuclear program because we see the negotiating process as being futile because they are lying whilst talking to us.
“They are lying whilst talking to the United States and other allies.”

He also suggested the Israeli war cabinet was discussing Iran’s Supreme Leader Ayatollah Ali Khamenei, after reports Mr Trump vetoed an Israeli plan to kill him.
“Let’s just remember that the Supreme Leader of Iran has for years called for the annihilation of Israel.”
Iran’s response to Israeli attacks on its nuclear facilities is “self-defence” and a “matter of principle”, the Iranian ambassador to the UK has told Sky News.
Speaking exclusively to The World With Yalda Hakim, Seyed Ali Mousavi said the “barbaric Israeli regime” is “violating international law” – describing Israel’s actions in recent days as “an act of aggression against the Iranian people”.
The conflict between Israel and Iran – once played out in a series of proxy wars – has escalated in the past three days.

When questioned about whether Iran could continue fighting Israel, the Iranian ambassador told Yalda Hakim that “it is a matter of principle”.
He said: “This is about self-defence, there is no doubt about it.
“We are a responsible member state of the UN and we do all activities according to our international obligations.
“Any activities are only in the framework of self-defence.”

He added that his country would “do our best to preserve our territorial integrity”, and that “with the help of God”, Iran will “materialise endeavours concretely against our enemy – the Israeli regime”.
Mr Mousavi also told Hakim that Iran’s nuclear activities are “monitored”, and that recent comments by the International Atomic Energy Agency (IAEA) were “politically motivated”.

Missiles have also been seen over Tel Aviv
The UN nuclear watchdog’s board of governors found Iran was not complying with its nuclear obligations for the first time in 20 years.
Iran said it has “always adhered” to the safeguarding obligations laid down by the watchdog.

Iranian ambassador reacts to strikes – full interview
Announcing Operation Rising Lion on Friday, Israeli Prime Minister Benjamin Netanyahu claimed Iran had recently taken steps to weaponise enriched uranium, which could be used to make nuclear weapons.
But Mr Mousavi stressed that Iran’s “peaceful activities” at its “nuclear fields” were only for the “generation of electricity, and other peaceful” things.
Iran was due to continue its round of negotiations with the US in Muscat – however, this was cancelled, given recent tensions.
The government is warning people not to travel to Israel under any circumstances, as the country’s missile exchange with Iran shows no sign of abating.
On Friday, the Foreign Office warned against “all but essential travel” to most of Israel.
The areas around Gaza, the West Bank and the Golan Heights were already classed as red zones, with warnings to avoid travel to these areas.
But the government has now updated the warning for the remainder of the country to red.
This puts Israel on the same level as Iran, and the change of advice is also likely to impact travel insurance.
However, with Israel’s airspace closed, it is unlikely many people will be attempting the journey, and Israel’s national airline El Al has announced it is cancelling flights to and from many European cities, as well as Tokyo and Moscow, until 23 June.
The change in travel advice comes after a second night of ballistic missile barrages from Iran following Israel’s attack in the early hours of Friday morning.

An eight-storey residential building in Tel Aviv was hit by a missile last night.
On Sunday morning, Israel’s health ministry said 12 people had been killed over the past day, taking the total since Friday to 15. It also said 385 people had arrived at hospital with injuries overnight.
Iran has not provided a total number of deaths or overall casualties, but has claimed dozens have been killed.
Iran’s health minister has said most of those injured and killed in Israeli strikes were civilians. According to comments carried by news agency IRNA, he said the majority were women and children.

The chancellor said UK forces could “potentially” be used to help defend Israel.
The UK government is sending military assets, including fighter jets, to the Middle East.
While the prime minister would not confirm to reporters that UK forces could be used to defend Israel from future Iranian attacks, the chancellor told Sky News earlier that the government is “not ruling anything out”.
Speaking to Sky’s Sunday Morning With Trevor Phillips, Rachel Reeves said sending military assets to the Middle East “does not mean that we are at war”, and emphasised that “we have not been involved in these strikes or this conflict”.
“But we do have important assets in the region,” she continued. “And it is right that we send jets to protect them. And that’s what we’ve done. It’s a precautionary move, and at the same time, we are urging de-escalation.”
Pushed on the question of what the UK would do if Israel asked for support with its operations, the chancellor replied: “I’m not going to rule anything out at this stage. It’s a fast-moving situation, a very volatile situation. But we don’t want to see escalation.”
