IRAN’S president yesterday issued a direct threat to the West, claiming his country is capable of revitalising its nuclear programme within hours.

Hassan Rouhani also said the country could quickly bring the nuclear programme to even more advanced levels than when Iran reached a deal with world powers that limited its ability to produce nuclear weapons.

His remarks to politicians follow the Iranian parliament’s move earlier this week to increase spending on the country’s ballistic missile programme and the foreign operations of its paramilitary Revolutionary Guard.

The bill – and Rouhani’s comments – are seen as a direct response to new US legislation earlier this month that imposed mandatory penalties on people involved in Iran’s ballistic missile programme and anyone who does business with them.

The US legislation also applies terrorism sanctions to the Revolutionary Guard and enforces an existing arms embargo.

If Washington continues with “threats and sanctions” against Iran, Rouhani said in parliament, Tehran could easily restart the nuclear programme.

“In an hour and a day, Iran could return to a more advanced (nuclear) level than at the beginning of the negotiations” that preceded the 2015 deal, Rouhani said.

The landmark agreement between Iran and world powers two years ago capped Iran’s uranium enrichment levels in return for the lifting of international sanctions.

The US and other world powers fear Iran sought the ability to produce atomic weapons. Iran has long denied that it seeks nuclear arms and says its nuclear programme is only for peaceful purposes.

It was not immediately clear what Rouhani was referring to – and whether he meant Iran could restart centrifuges enriching uranium to higher and more dangerous levels. He also offered no evidence of Iran’s capability to rapidly restart higher enrichment, though Iran still has its stock of centrifuges.

Those devices now churn out uranium to low levels that can range from use as reactor fuel and for medical and research purposes, but could produce the much higher levels needed for a nuclear weapon.

However, in December Rouhani ordered plans on building nuclear-powered ships, something that appears to be allowed under the nuclear deal.

Rouhani’s remarks were likely an attempt to appease hard-liners who have demanded a tougher stand against the US. But they are also expected to ratchet up tensions further with the Trump administration.

Iran has said the new US sanctions amount to a “hostile” breach of the 2015 nuclear deal. But Rouhani also tempered his own threat, adding that Iran seeks to remain loyal to its commitments under the nuclear deal.
