“…the strong do what they can and the weak suffer what they must.” Thucydides, The Melian Dialog
“if any two men desire the same thing, which nevertheless they cannot both enjoy, they become enemies; and in the way to their end (which is principally their own conservation, and sometimes their delectation only) endeavour to destroy or subdue one another.”
“A law of nature, lex naturalis, is a precept, or general rule, found out by reason, by which a man is forbidden to do that which is destructive of his life, or taketh away the means of preserving the same, and to omit that by which he thinketh it may be best preserved.”
“Hereby it is manifest that during the time men live without a common power to keep them all in awe, they are in that condition which is called war; and such a war as is of every man against every man. For war consisteth not in battle only, or the act of fighting, but in a tract of time, wherein the will to contend by battle is sufficiently known: and therefore the notion of time is to be considered in the nature of war, as it is in the nature of weather.”
(Contrast this with classical realism.)

“Violence and war are never finally located in any of the three images for Kegley. This is because war and conflict—bad behavior—can be eliminated if only political and social arrangements are better organized” (41).
Constructivism is a structural theory of the international system that makes the following core claims: (1) states are the principal units of analysis for international political theory; (2) the key structures in the states system are intersubjective, rather than material;
(3) state identities and interests are in important part constructed by these social structures, rather than given exogenously to the system by human nature or domestic politics.
