The P5+1 countries in the Istanbul talks with Iran are the five permanent members of the Security Council and Germany. Catherine Ashton, the EU's senior foreign policy official is the lead negotiator. Saeed Jalili is the lead Iranian negotiator. By July the two groups have held three rounds of talks which proved inconclusive and were lowered to meetings at the deputy level in July, 2012. This was followed by bellicose statements from Iran and U.S. defense preparations in the Gulf of Hormuz. The Israelis described the situation as reaching a critical point, with the U.S. continuing to put its faith in tighter sanctions to persuade Iran to give up its program.
