I heard that, too, but I think there's a different possibility: Brian also said it was first reported in Reuters, thus it may have been a lie and not a reflection of any inconsistency in Israel's actual position. Jennifer said she had confirmed it with an "Israeli official," and we all know this could be anyone, including the janitor, who might not have had any actual information. Sooooo, the first source of this may have been erroneous. I don't see Israel allowing any possible split (even assuming there is one) in their position becoming public.
Jennifer is excellent for the most part. I think she would use a solid source (however wrong he or she might have been).
