I've suspected that when Prime Minister Binyamin Netanyahu visited the US earlier in the spring, President Barack Obama laid down some lines on Israel's behavior. This small bit of news isn't enough to support that idea, but I'd like to note it for future reference.
Last week, the Global Counterterrorism Forum held its first meeting. Without Israel. Turkey is the co-convenor of the Forum, with the United States, and the rumor circulated that Turkey had insisted on excluding Israel. The official US statement on that subject was noncommittal.
Later news reports from Israel are more mixed, but some sense of exclusion remains.
