Richard III, why become a soldier?

I'm very interested in military history, and the question why people choose to be soldiers. Is it the exitement to move outside the rules of the society; kill whom you want without any concequenses? Is it about adrenaline kick; a kind of bungee jumping. I've met some norwegian soldiers serving in Afganistan and Lebanon. My opinion is that we need a millitary force, and that we have to give those women and men the respect they deserve doing their duty. Off course Norway as number seven in the international arm production have a great interst that there are wars. But I think that the armed forces are important not only to protect or expand our economic interests. For me it is about the person who is a soldier, and that the reason we have had peace in the western Europe for ower sixty years. It's naive to think that we can be without armed forces to defend, or to do peace creating operatioms. So I would like to make this as a theme in my next opera project with my libretist Ketil J. Zahl who is a military historian.
