Some friends of Israel, and many Israelis themselves, have been so forensic in picking through references to Israel in President Obama's Cairo speech that, to quote him from a press conference statement in Paris on Saturday, while “I've discussed the importance of a cessation of settlement construction... I also want to reemphasise, because that's gotten more attention than what I've also said, which is the Palestinians have to renounce violence, end incitement, improve their governance capacity so that Israelis can be confident that the Palestinians can follow through on any commitments they make across the table." Few commentators have so far seriously assessed what improving governance capacity means. In the first place, it must mean ending the internal strife between the Palestinian factions. Within the past 24 hours, Fatah has arrested Hamas members in the West Bank and Hamas has rounded up Fatah followers in Gaza, including one who reportedly died of a heart attack when apprehended and another who was accused of spying - he was charged with passsing information about Hamas to the Paletinian Authority. Every effort made by Cairo and others to bring the two sides to an agreement has collapsed. A final “reconciliation” meeting is due in Egypt on July 5. There is absolutely nothing to suggest it will be any more successful than the others. Mr Obama might yet find - like virtually every one of his predecessors - that his vision of peace is frustrated not so much by Israeli obduracy as by the inability of Palestinian leaders to stop burying the hatchet in their brothers' heads.
