The armed forces in the US are VOLUNTARY. I know a few young people in the military (men and women) and every single one has said the same thing, 'those that have already seen a tour in Iraq want to go back'. I know of no one who is afraid of returning service people. I do know of plenty people who are frightened by the gangs in the cities, the mental patients walking the streets and illegal aliens who commit crimes only to be returned to the country of origin or put up in prison at our expense.
Have you ever talked to a vet? To get a balanced view you may want to vistit you local VFW Hall and see the many, many different views of how returning from war affects the many different personalities. They are not all insane. My neighbor recently returned from Iraq, he appears quite normal, goes to work, plays with his children and seems to love his wife.His entire street was lined with flags and welcome home signs. Could he snap at some point due to the horrors of war? Yes. So can ex jw's from the horrors of spiritual, emotional, physical, and sexual abuses. What is the government or churches doing about that?
Your average EMT worker in a large city sees more horrors than your average soldier, warrior, or sailor in a tour of war. I say average, there are the exceptions of course. Peeling kids off the pavement every other night, putting people in body bags on a near daily basis, seeing the despair of suicide, etc...etc... From what I hear from military types is the tour is usually about 6 months and they return home. Those with specialized services (which they volunteered for) have to stay longer because there are not as many of them with a certain skill. Some serve and see no 'actual hand to hand' much is not 'seen' by the individual, many bombs and 'knowing' but not actual visual images.
If someone gave me the choice, would you rather have an ex military who has seen war move in next to you or a jw what would you choose? I would choose the military any day. I find them far less dangerous to ones being.
