Pope, Jason: I honestly do not mean to offend. I do not, however, understand how arguing about definitions can possibly offend. I am not denegrating combat veterans by arguing that something should be named more appropriately.
The 'effete liberal sentiments' I have so far espoused are that criminal acts should be dealt with by police action and that words should be used consistently. I have never implied that the military have no place carrying out police action in certain circumstances (which you seem to take I mean). You seem keen to apply labels to what I am saying without good reason.
You note that people are dying, therefore this is war. The analogy is false. People die all the time for lots of reasons, and applying the label of war there would be equally fallacious (natural causes, firearms, accidents etc).
In you ultimate rhetorical question you seem to imply that there are two causes of action, which you name realism and idealism. In the former, one shoots the man who tries to shoot one. In the latter, one simply asks 'why?' and does not protect oneself. You then ask which camp I identify with as though my response would mean that I would have to support another position regarding a completely different situation. Obviously, if being shot at I would protect myself and others. But we are talking about how to deal with people who want to send others to commit mass murder. Simplistic strawman analogies get nowhere.
RC: Depending on how you look at it, you can claim that wars are mass actions of large collections of individuals. But the crucial difference is that these individuals are aligned to a nation, such that it is the nations that utilise the individuals to conduct the war. A riot fits the former, but not the latter criterion, therefore we do not call a riot a war on shop fronts.
Motivation does not affect whether we call something war. War can be for profit or war can be for presevation of the nation.
The Illiad describes the war of Troy, where the Greek kingdom (of Menelaos?) attacked the kingdom of Troy, thus satisfying the national combat criterion. Also, I would not define battles as necessarily occuring within the context of a war.
