War and violence have a lessened impact on Americans however this is mostly due to the fact that it never occurs close to home. However while lessened the reactions of fear and bigotry are largely the same. For instance when the war with Iraq started people became less trusting of anyone from the Middle East and some even beat up people from there. They just assume that if you were Muslim it must make you a terrorist and you should be punished or shunned for the beliefs that you hold. As for its effect on children I can say that it is nowhere near as bad as using them for soldiers but it can be bad for their ideals. Scared parents teach their children and in times of war it can give birth to new negative views of other ethnicities, races, and cultures. It’s passing down the old hatreds to the new generation and it’s been going on for centuries.
