Israel therefore needs to demonstrate its earnestness and political will on the path of peace and to turn words into deeds, especially given the momentum that has been generated by the Annapolis peace conference, by abjuring policies that contravene international law, undermine international conferences and initiatives and peace opportunities, and make the task of the Quartet more difficult.
Israël doit donc prouver sa détermination et sa volonté politique d'avancer sur le chemin de la paix et de transposer les discours en actes, surtout si l'on considère l'élan insufflé par la conférence de paix d'Annapolis, en abandonnant sa politique qui contrevient au droit international, sape les conférences ou initiatives internationales et gâche les chances de paix, compliquant du même coup la tâche du Quatuor.
