Of course it's not and you won't find him wanting your sympathy either. I went to Afghanistan for three months and, to be honest, I loved it. Alright the food was shit, the weather worse and there were some ****ing nasty creatures knocking around (and no, I didn't try and sleep with them!). But I spent 18 months training for a tour like that and I relished the chance to apply my skills. Not once did I think about the rights or wrongs and all the political bollocks and I don't recall hearing anyone else doing so either. My folks didn't worry too much either, perhaps because I was in the RAF and we didn't go on patrol, but I would never have wanted them to challenge the authorities on our right to be there should the worst have happened to me.
Anyway Siouxie I am sure he will really appreciate whatever you send him as there will be many hours where you are sat doing nothing.
