Yes, its true, there is a high rate of mental illness in returning service men and women - this is because, in my opinion, war is not a organic state of humans - people have to be forced to do it and it makes a lot of them ill - war is pathological - every-time there is also a war, afterwards there is some type of massive societal damage - even if the society was not damaged directly by the conflict - it comes from returned soldiers - my two cents,

Thanks!
