Iran has long considered the appropriate responses to the possible quit of the nuclear deal by the US, he said, adding that “we hope the Americans do not drop the deal … since it would be a scientific challenge for them.” On Thursday, Salehi warned the US not to make any more move against the 2015 Iranian nuclear deal. “We are seriously looking to preserve our national interests and sovereignty, but if the United States withdraws and Europe and other great powers retreat from this agreement, we will definitely do something different,” said Salehi.
