Another delicate issue could be determined by the Heads of State or Government
status. Because they are the ultimate authority in a state, they cannot delegate the
decision role when a deadline is too small (Berridge, 2010, p. 164). This fact does
not allow an efficient analysis of the problem. In this situation, Berridge notices
two mistakes that leaders could do: to abandon the negotiations, leading to a
diplomatic failure or to accept too many concessions to provide purposeful
diplomatic activity (Berridge, 2010, p. 164). The second mistake is even worse
because it is not only eventually followed by a “too expensive” deal, but is also
irreversible and it has long period effects.
