Mr. Rouhani said the US would undoubtedly regret if it violates the deal. The Iranian president made the remarks while visiting New Delhi on Saturday. The announcement was released after US President Donald Trump is threatening to withdraw from the historical nuclear agreement known as the Joint Comprehensive Plan of Action (JCPOA) and to re-impose sanctions against Tehran. Rouhani stressed that JCPOA can’t be re-discussed despite the threatening from the US.
