War is a lesser of two evils, sadly required to protect our nation and to liberate the oppressed people of the world. In response to the September 11 terror attacks, the U.S. waged war out of self-defense. The World Trade Center was not the only thing that was destroyed that day. Our sense of nationalistic pride and dignity was diminished by these terrorist. How could we stand and watch as one of the greatest American symbols collapsed? In order to reclaim our sense of dignity, war was the only option. Self-defense is a universal characteristic of all humans, and war was just that. Humans were ultimately bred for war. Natural selection favors the survival of the fittest, which drives us to be the best we can be and dominate others if necessary. What's war but another form of domination? How can anyone go tell millions of Jews to go back to concentration camps because the war we waged on their behalf against Hitler was unnecessary or a mistake? As gruesome and terrible war may be, it is undeniably a trademark of any and every society. War has always been present in the past, continues to exist today, and will persist throughout the long future. War is not something that is simply waged, it is something that we, as humans, will forever carry with us.
