The three easiest ways to start a war seem to be: question someone's parentage/legitimacy, question their religion, or just think you personally are better suited to lead a particular country. Sure, there are some purely political wars...
The first sentence excludes Civil War. Is civil war considered a type of war?
Two questions: (1) which Geneva convention? There are actually several Geneva conventions relating to the rules of law, so we normally say "Geneva conventions", not "Geneva convention". Could you please quote the full title of the convention(s) in question?
(2) what are the "formal criteria" that determine what is a "war" and what is an "armed conflict"? Is it a question of whether it is of international character (wars between states) or an internal war (civil wars, rebellions, etc.)? -- SJK
Bad example then. Anything to add perhaps? --Anders Törlind.
War is the health of the state. It automatically sets in motion throughout society those irresistible forces for uniformity, for passionate cooperation with the government in coercing into obedience the minority groups and individuals which lack the larger herd sense . . . In a nation at war, every citizen identifies himself with the whole, and feels immensely strengthened in that identification . . . He achieves a superb self-assurance, an intuition of the rightness of all his ideas and emotions, so that in the suppression of opponents or heretics he is invincibly strong; he feels behind him all the power of the collective community. - [Randolph Bourne]?
