Negotiations and conflicts on the international stage are only for true masters of negotiation and communication. They are very often multilateral negotiations and therefore involve a large number of conflicting interests, which make it very difficult or even impossible to maintain an overview and, above all, to work out joint solutions. In contrast to "pure" business negotiations, not only are the interests of the negotiating partners diametrically opposed, but many other immensely complicated factors also play a role. 

Different cultures, geopolitical interests, different histories and political interdependencies make such negotiations extremely difficult. The additional factor of "power", especially in the interaction between states, usually leaves no room for maneuver for productive and therefore successful negotiations or conflict resolution; supposed compromises are only generated under pressure, making "bad" deals possible. 

The "powerful one" is getting bigger and bigger,
the "weak" is getting smaller and smaller.
