The current diplomatic situation can be described as tumultuous. Just as the United States strengthens its military deployments in the Middle East and regional tensions escalate, Iran has proposed new adjustments to the meeting originally scheduled for this Friday in Istanbul, Turkey. Tehran not only advocates moving the location of the bilateral contact with the United States to Oman but also explicitly demands that the negotiation topics be strictly limited to nuclear issues. This temporary change regarding the meeting location and agenda undoubtedly adds more uncertainty to the already challenging diplomatic mediation efforts.
