I lived in Germany for three years as a young boy. I do remember it quite well. The funny thing is, when you talk to some of these vets, a lot of them empathize with their "enemies". I think each side rationalizes it as either "it's him or it's me" or I was doing what my country asked of me and I think we can empathize a lot with that. Especially with WW1- there were a lot of different actors involved with that one- Germany wasn't the Nazi power and hadn't gone down that road.
I believe all vets, once they return, have to live with two things and seek forgiveness/ make reconciliation for these things:
1.) They have to recover from the sheer horror of the tragedy that happened to their friends and the psychological trauma of nearly dying themselves and dealing with the intense stress of being exposed to such a stressful environment for such a length of time and
2.) They need to reconcile with the killing that they did. It is easy, I think to kill another man as a younger man. Myself, I see it so differently now being a father- no matter how cruel or twisted the other man may seem, he was a young boy like any of my children. I am sure many men have returned and had to deal with that. Killing people is not part of God's plan nor part of sane human psychology. To have to do that and then return back into a normal, civilized society must be hard.
They say my great grandfather who fought for the US in WW1 had a bullet lodged in the top of his head. It is true, he had a bump right on the top of his head. They say the bullet hit his helmet and lost a lot of its momentum but was able to penetrate the skin and went under the skin and stayed there on top of the skull but under the skin. Who knows??
Yeah, I couldn't imagine lying in a trench with a bayonet stuck through my leg. I couldn't imagine going through the horrors of WW1 and it should have been the war to end all wars but here we are, still beating ourselves to a pulp with bigger bombs and deadlier weapons. Sorry to sound like such a Peacenik- I guess I just despair when I hear stories like this, and they are in such an abundance. I just get sad thinking that if things go horribly wrong, that might be one of my sons ( or heaven forbid my daughter) lying in a trench, field, jungle, etc slowly bleeding away........
