Iran has given Trump what Americans call an off-ramp

Let's hope John Mearsheimer is right to be hopeful.

'Trump emphasized in his talk [State of the Union address] that Iran cannot have nuclear weapons, but that he has yet to hear these “secret words” from Iran: “we will never have a nuclear weapon.”

'The Iranian Foreign Minister, however, said just before Trump’s address that “Our fundamental convictions are crystal clear: Iran will under no circumstances ever develop nuclear weapons.” That statement should satisfy Trump’s demand.'
