President Biden must “compensate” the regime in Tehran for former President Donald Trump’s decision to withdraw from the 2015 Iran nuclear accord in order to rehabilitate the pact, according to a senior Iranian diplomat.

“The onus is on the offending party to return, restart, and compensate for the damages as well as to reassure that they would not renege again,” Iranian Ambassador Esmaeil Baghaei Hamaneh, Tehran’s top representative to the United Nations in Geneva, told the U.N. Conference on Disarmament on Wednesday.
