He'd be silly to say anything else, because as the weaker party, they're in a no-win situation. Refuse to talk cos it's obvious the Israelis are just using them to stall and you become the bad guy. Go into the talks but say they're doomed to fail and you become the bad guy. so you go in and say all is well in the garden and allow the Israelis to sabotage them, why do their work for them ?

However, whether that reflects their real feelings about the process I would say it was unlikely.
