Under the Trump administration, the US imposed crippling sanctions on Iran after Donald Trump withdrew from the Iranian nuclear agreement in 2018. Washington was seeking an extension of a United Nations (UN) arms embargo against Tehran.
The nuclear deal had restricted Iran’s nuclear weapons capability in return for sanctions relief.
However, Iranian state-media, Press TV, has boasted about its “sophisticated weapons” despite pressure from the west.
Press TV raged on Twitter: “Did you know that Iran has managed to make sophisticated weapons under unprecedented pressure and arms sales embargo?”
Last month, President Joe Biden indicated an interest in turning a page on US-Iranian relations as he addressed the UN General Assembly (UNGA).
Mr Biden said the US would return to “full compliance” with the deal negotiated during his previous stint in the White House under former President Barack Obama.
He said: “The United States remains committed to preventing Iran from gaining a nuclear weapon.
“We are working with the P5+1 to engage Iran diplomatically and seek a return to the JCPOA.
“We’re prepared to return to full compliance if Iran does the same.”
However, in December Iran told the United Nations’ nuclear watchdog it plans to install three more clusters of advanced IR-2m centrifuges at its underground uranium enrichment plant at Natanz.
The agency wrote: “Iran informed the Agency that the operator of the Fuel Enrichment Plant (FEP) at Natanz ‘intends to start the installation of three cascades of IR-2m centrifuge machines’ at FEP.”
They added these were in addition to one of IR-2m machines already used for enrichment there.
In July this year, the Pentagon warned a nuclear war could happen as Iran and other countries have armed themselves with terrifying nuclear weapons.
According to the report, Iran is believed to have the technology to create a nuclear weapon within a year.
Last year, the Iranian Revolutionary Guard Corps unveiled a terrifying new missile, which was described as a “new generation of naval ballistic missiles bearing the name of Zolfaghar Basir”.
According to Tasnim news agency, the range is more than twice that of Iran’s other naval missiles, including the Hormuz-2, which has a range of 300km and was successfully tested in 2017.
The news agency did not specify whether the new missile had been tested yet.
Washington and Tehran were at the brink of war in January last year after US forces killed Iranian major general Qassem Soleimani during a missile strike in Iraq.
General Soleimani’s convoy was struck by three US missiles.
Days after the attack, Tehran retaliated and launched a series of ballistic missiles at two Iraqi bases housing US troops.
