Why We Fight?

Here’s a sentence from a student’s essay concerning war’s justification or lack thereof.  They just finished reading All Quiet on the Western Front, and I asked them to consider the reasons for war against the actions in war.  After describing the brutality of WWI, he wrote, “In my eyes, there is no such better way of solving conflicts because there is no such thing as peace without the crazy people who cause violence and are, quite frankly, worth killing to obtain peace…Without these moments there is no peace in the world because peace doesn’t exist without violence.”

What do you think?
