As a reminder, the mood when we returned last week was that the deal was "imminent". One week later, we're still caught in the same negotiating position once again.The US and Iran are continuing exchanging military blows in trying to posture ahead of the supposed framework agreement or memorandum of understanding (MOU). However, the latest communique from both sides continue to indicate a standoff between them.US president Trump wants Iran to at least commit to a baseline guarantee on nuclear/uranium. And that sees a constant change in the terms that both sides are seeking from the deal/MOU. As for Iran, they continue to defend that they will not make any commitments on nuclear/uranium. That led to chief negotiator Ghalibaf blasting the US for "frequent changes" to the agreement terms.Both sides continue to maintain that they are "very close" to signing off on a deal/MOU. But again as mentioned last week, nothing can be agreed until everything is agreed upon.It is not just one thing that needs to stick, there are four key terms that both sides need in order to proceed to the next step. And more importantly, these terms need to hold for the 60-day duration set out for the next round of negotiations.From last week:US and Iran know what the puzzle pieces are, but can they fit them all together?Deal or no deal?
