Today's international system

a. is beset by too many forces for change to allow anyone to be able truly to predict the course of the future. b. offers us a rather easily predictable future assuming that major North–South conflicts do not occur. c. is in most ways similar to the system created by the Treaty of Westphalia in 1648. Few changes have taken place, and few changes are foreseeable for the future. d. is beset by international conflicts caused almost exclusively by the advance of science and technology. If this forward rush can be harnessed and controlled, it is likely that conflict can be reduced and even eliminated in the present system.
