A sane person doesn't think war is a good idea.
It sounds strange to say it, but you can be in a war zone and have a lot of fun. Even though war is essentially pain on all sides, human beings have the capacity to enjoy themselves. The soldiers are mostly young people, full of enthusiasm and energy, and that's an exciting thing for an old guy like me.
Since the early '80s, I've found myself in war zones in various parts of the world.
