I listened carefully to Mahmoud Abbas’ speech to the United Nations Thursday. It was peppered with a lot of obnoxious comments, evidently aimed at scoring points in some intra-Palestinian competition with Hamas. (Two mentions of “apartheid” in one speech? Really? Don’t they have a thesaurus in the PLO speech-writing office?) Bizarrely, the speech made no mention of the just-ended Hamas rocket war against Israel. But it was striking to me that the speech’s overall tone was conciliatory, not provocative.
