The letter US President Donald Trump sent to Iranian Supreme Leader Ayatollah Ali Khamenei earlier this month included a two-month deadline for reaching a new nuclear deal, according to a report by Axios. The letter proposed renewed nuclear talks between the US and Iran, while threatening Tehran with consequences should it continue pursuing its nuclear program. It is unclear when the two-month countdown began. Trump revealed the letter's existence in an interview, stating that he preferred to make a deal with Iran rather than resort to military action.
