War and genocide; is there a difference?

Is war any different than genocide? Both consist of the killing of a certain target group set in order by authoritative figures supported by majority of a group. The major difference that sets them apart is the type of justification given for support. One can argue other simplistic arguments of the difference between the two, but in the end when it comes right down to it, both are the killing of another human being supported by respective societal figures. Yes, killing of another human being will occur outside of war and genocide, but the mortality rate for large groups of people at a single moment in time would decrease. In the United States in 2004, there were 17,357 homicide deaths with an overall death rate of 5.9 per 100,000 (Minineo et al., 2007). Homicide is classified as an act by one human being that is intended to or actually does kill another human being. The homicide rates have been trending upward since the late 1980's (with a sharp spike in 2001 resulting from deaths associated with the September 11 attacks on America)(Corr et al., 2009). Outside of the definition stating the killing of another human being, war and genocide is basically homicide. Sometimes it isn’t just an individual, but a group of individuals that take action to kill other human-beings; in all its human-beings killing other human-beings. To arrange for and bring about large numbers of death requires extensive and systemic organization, involving legal, economic, military, and political structures, sometimes along with educational and scientific research structures(Corr et al., 2009)

What would come of this world, and the death system if people would only concern themselves in matters of violence when it directly effects them personally not indirectly. What would happen if people set down and actually thought about what another person is asking them to do. What would happen if people only feared God and not man.

For someone to gain control of a society they must invoke a fear unlike any other, and than promise a protection that they only can give.
