when Iran student revolutionaries stormed the US

embassy in Tehran, holding 52 diplomats captive for 444 days.

Fourty years on, and the former embassy

is now a museum run by the Islamic Revolutionary Guard.

A visit here is a journey back in time.

On display, document disposers and satellite transmitters,

equipment the hostage takers believed

the US was using in its attempts to undermine the revolution.

Earlier that year Iranians had overthrown the monarch

and the country had voted to establish an Islamic republic.

Their actions still echo through these rooms and corridors

and onto the global stage.

Iran and the US remain arch enemies.

All nations have a duty to act.

No responsible government should subsidise Iran's bloodlust.

In 2018, US President Donald Trump

pulled out of the nuclear accord and imposed the toughest

sanctions ever against the republic.

Iran has vowed not to retreat from its ballistic missile

programme.

Ordinary Iranians like Ali are suffering,

but he defends the hostage taking

and says Iran is right not to trust the US.

His wife Simin believes the country must maintain the power

to defend itself.

For Ramin, however, the hostage taking was a costly mistake.

Back at the embassy, the bubble room

was used for secure top-secret meetings.

Here, the diplomats allegedly plotted

against Iran and other regional powers,

free from eavesdroppers.

The embassy equipment may look outdated now,

but the mistrust between the US and Iran is current and real.
