IRAQ and SYRIA

Secretary of State John Kerry arrived in Vienna yesterday for meetings with Iran, Russia, Saudi Arabia and Turkey ahead of today’s talks aimed at reaching a political resolution to the Syrian conflict. [Wall Street Journal’s Valentina Pop]  The peace negotiations getting underway today are the “broadest” to take place since the start of the conflict in 2011, with “any hope of a solution” riding on Iran and Saudi Arabia, the former advocating in support of the Assad regime and the latter against it, reports Martin Chulov. [The Guardian]

“Rancor” between rivals Saudi Arabia and Iran poses the greatest threat to the talks, with “more invested in the outcome” than any of the other participants to the talks. The two states sitting together at the same table was “unthinkable” until two weeks ago. David E. Sanger et al report. [New York Times]

[Foreign Policy]

Iran’s role in the Syria talks demonstrates again that “defiant Iranian rhetoric is often a distraction from Iranian actions, which may be more pragmatic,” writes Roger Cohen at the New York Times.
