importance of military

In my opinoin each country needs a military. It would be nice to have a whole world without it,but reality is different. Military should be not for fighting the other countries , but for protecting each country from outside or inside enemies.Its impotant to train the military and have a new soldiers because you never know when war might happen.Military has changed many people who would not be who they are today wihout the discipline military gave them.The military has helped teenagers who have been bad during their adolescence to change into someone with a future.The military made a huge difference to a lot of peoples' lives.It has also helped to get an education and experience new things.The military is important in our lives because if another war break out,those soldiers will risk their lives to save ours.
