Is the military in yout future?

In my homecountry, Japan, they do not require military services. The military in Japan, is composed of people who wants to be in soilder, or a child of the solider. So its not required for a normal citizens. Although, the time during World War 2, all of the men were required to be a solider. (even a small kids like 12) From this, I guess when a war happens again, such as World War 3, I think I am required to be a soldier. If that happens, I think I will run away somewhere safe, because I dont like fightings, and mostly, I dont want to die. The time when I WILL join military, is only when I'm so angry that my surroundings were killed. (Such as family) Thats the only condition when I would go to military, because I don't really think I could save Japan from other big countries like America.
