There is no doubt that many innocent civilians and children get killed during times of war. I think that war is morally permissible because when one country thinks that they have power over another they will eventually feel that way about every country. They will try to take on the world in order to be the sole power. There is no reason why other countries such as the United States should not stand up and fight for what they believe in. After all, the United States is based upon freedon and if some other country has control over our freedom than it is not really freedom that we have.
Wars do create more chaos for a country.
The economy can sometimes fluctuate so greatly that it may never get back to the way it was. This may sound pretty selfish but we have to fight for what we believe in. The previous wars have taught us so many things. One thing that has been learned is that the United States is a very powerful country. I would rather be looked upon as a strong nation verses a weak one who has to rely on other countries for support economically and so on.
