Al Jazeera reports that a conference currently underway in Tehran may be the "latest (if not last) opportunity" for Iran and Gulf states to restore diplomacy, in response to the tangible risk of military escalation between the United States and Iran. The report notes that Iranian officials are showing decreasing interest in the closed-door discussions. A senior Iranian official described the Qatari delegation's visit as "routine exchanges," but Al Jazeera believes this is not a "routine period." While Iran signals its readiness for diplomatic engagement, the U.S. and Iran remain far apart on contentious issues. The conference may also aim to convey the "red lines" of the involved countries should confrontation resume.
