On the subject of the JCPOA, US Treasury Secretary Steven Mnuchin stated yesterday that the US might impose “very strong” sanctions on Iran in the event that the “disastrous flaws” of the nuclear agreement (as referred to by President Trump) are not addressed before the 12 May deadline. He said that the US administration were considering both a fresh round of sanctions, as well as the return of previous sanctions that had been waived as part of the JCPOA.
