It is interesting the amount of replies thus far that are hesitant to find a common goal, or say it can not be done.
I see a world in need of a universal cause and this advice following, I see will unfold;
".....The time must come when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world's Great Peace amongst men. Such a peace demandeth that the Great Powers should resolve, for the sake of the tranquillity of the peoples of the earth, to be fully reconciled among themselves. Should any king take up arms against another, all should unitedly arise and prevent him...."
The events of our current day are adding to the convulsions that will lead to a world that seeds the need for such actions.
All the best to all.
