Iran’s officials have promised a “special surprise” if the Trump Administration withdraws from the July 2015 nuclear agreement between Tehran and the 5+1 Powers.

Ali Akbar Salehi (pictured), the head of the Atomic Energy Organization, put out the message:

The enemies should know that in case of a JCPOA [Joint Comprehensive Plan of Action] rollback — even though we are never looking for such a situation — special conditions will arise, and when the high ranking officials decide, there will be a special surprise for those who scuttle the agreement.

Salehi did not specify the “surprise”, but analysts believe Iran will soon resume enrichment of 20% uranium and pursue more powerful and efficient nuclear centrifuges.

Under the deal, Iran agreed to halt production of 20% uranium — which potentially can be further enriched to military-grade 95% uranium — and to send all stocks abroad. Tehran also suspended its plans for research and development of centrifuges which could yield the enriched uranium far more quickly.

While imposing new sanctions on Iran, the Trump Administration has so far held off on withdrawal from the agreement. However, Donald Trump — who has repeatedly denounced the “worst deal ever” — may refuse to extend a waiver on broader, Congressionally-mandated sanctions in mid-May, effectively scuttling the JCPOA.

Iran has courted the European signatories of the deal — the UK, France, and Germany — to maintain the accord and to distance themselves from the US if Trump does not sign the waiver by a May 12 deadline.

The Chairman of Parliament’s National Security Committee, Alaeddin Boroujerdi, extended Salehi’s warning on Saturday, saying, “If…sanctions are re-imposed on Iran, we definitely will not remain in the JCPOA.”
