I don't understand this logic of Israelis attacking the Iranian delegation? Weren't there some news a few days ago that Pakistan prevailed upon Israel, through America, to not target the remaining Iranian leadership? And thus we see recently some of the topmost Iranian leaders out in the public.
As much as the Israelis don't like this 'ceasefire' even they wouldn't dare sabotage the Islamabad talks coming up. I think Israelis attention has now shifted to Lebanon to 'degrade' Hezbollah enough so that Israel can gobble up southern Lebanon. I don't think Israelis care about Iran much anymore at this point.
