Foreign Secretary expresses concern about violence in Cairo... Too little, too late?

On the 5th of December, Foreign Secretary William Hague stated: "We urge all parties to resolve their differences through a process of dialogue which allows all voices to be heard.”

Not only is this months too late, but what process of dialogue allows all voices to be heard? Who will be involved in this dialogue? And when exactly will it be held?

Will dialogue between fundamentalist Morsi and his opponents be successful in stopping the violence or is it an empty promise?
