A mish-mash of rationales regarding this "vets' competency" nonsense I've heard by people I know (the latter portions are my attempt at completing the "logical" progression of each point)
1. Only highly trained soldiers can be relied upon to win battles--but training/experience makes them too effective to be trusted back home
2. Only psychos join the military-->but only psychos can perform as soldiers
3. Service makes soldiers crazy-->but it's okay; they were crazy to begin with
4. Veterans are incapable of reintegrating into society-->therefore they can never be fully trusted
Just a mess of conflicted logic and poor assumptions. But some people live by contradictions, it seems. The only way to satisfy the "constraints" of the caricatured viewpoints above is for our servicemen to completely dissappear before and after conflict--but somehow remain ever vigilant, and ever ready. And totally isolated from civilian society at all times.
I suppose the dream is that if we civilians can avoid the cost and risk of war to ourselves, we can wage it with impunity?
I can envision nothing more horrific than a warrior protected from all compassion for his enemies. If we more exposed to the true costs of conflict and to those affected by it, civlians would have both more reluctance to wage wars, and a better understanding of and respect for those returning--so they would not be treated as outsiders. War has become too pleasurable and convenient in it's mechanized, automated form.
