As the United States calls for a single position from Iran on peace talks, a key question remains: who is the regime's 'final decision-maker' — if there is one? The White House press secretary, Karoline Leavitt, has said recently that US President Donald Trump is looking for a "unified" response from Iran, adding that "there is a lot of internal division" in Iran.
USSC Associate Professor David Smith spoke with SBS News on the Trump administration's call for a "unified" response from Iran, saying "Trump is very frustrated by the lack of progress in negotiations. And so he is making this claim that the only reason why they're not progressing is because the Iranians don't have a unified response."
