Do we need War?

I think war is very important but not always necessary. I think it depends though on the reason for starting one. If it is just to get power then I think it is completely unnecessary but for example the whole Iraq thing i think that is important and here is why. When 9/11 happened it was a big deal as we all know because it was a ist attack on the USA. So the president sent our troops into Iraq to find the ist group that attacked us. Then it kind of turned into we need to defend this country against that one guy(gosh i can never remember his name) and the ost group he runs. we were defending and protecting our country but it turned into defending Iraq and Iran which i dont think we should have done unless they had asked us for help. So we were trying to protect Iraq but i dont think we should really get involved with that because then we could become more of a Target for ist attacks and its not in our country. I think it is important to really think over the reasons you would start dropping and sending out troops to another country before you start it so you would be sure it was the right thing to do. Would it be called ? I think yes it would but in the bible God tells David to go and kill all these people but they had sinned against the Lord. The Definition of is; the crime of unlawfully somebody with a malicious thought. so basically some person because you are mad or spiteful. I dont think the troops want to kill people but they want to defend their country to.
