Miltary In My Life

I come from the US so i dont have to serve but i can if I want to. I would join if the US joined in a war that i belived in and if it was the right thing to do. But if the US joined a war that was pointless and i didnt belive what they were doing was right then i probably wouldnt join. Another reason why I would join the army is if my country really needed me. I am thinking about doing a couple years in the army before college but that thought is still being decided. So over all I think the army may have a bit of influenc in my life but i am still not sure about it.
