KONFRONTASI-On August 19, 1953, an American-led military coup toppled Iran's first democratically elected government of Prime Minister Mohammad Mossadegh, a move described in a declassified CIA document "as an act of US foreign policy".
For the past 65 years, this event has continued to haunt the ties between Tehran and Washington - and in recent months has taken on a new significance amid a renewed diplomatic standoff between the two following US President Donald Trump's decision to withdraw from the 2015 nuclear deal and reimpose sanctions.
The move angered Tehran and prompted a range of reactions - from President Hassan Rouhani saying Iran will not negotiate while sanctions are in place, to the Supreme Leader Ayatollah Ali Khamenei declaring that all negotiations are off the table while Trump is president.
But if Mossadegh was in charge today, he would have engaged in direct talks with Trump, a former Iranian diplomat and current spokesman of the late leader's political party, National Front, told Al Jazeera.
"For Dr. Mossadegh, everything was towards the realisation of the country's national interest," Davoud Hermidas-Bavand said, addressing him by his title as a doctor of law.
"If he was alive today, and he was responsible for any decision for the country, he would have adopted the same approach he took in 1953, within the context of existing international framework and international values," added the 85-year-old.
In May 1953, just months before his ouster, Mossadegh ordered the government's takeover of the Anglo-Iranian Oil Company, now British Petroleum (BP).
The prime minister had contended that an oil exploration deal signed decades before favoured the British company, instead of the Iranian people.
But before going ahead with the takeover, Mossadegh had held months-long talks with the UK and the US to reach a compromise. The dispute went all the way to the International Court, which sided with Iran.
