If Peace is the Price, Then What’s the Prize?

Let's remember our fallen soldiers. A few pay the price with their lives so that the rest can enjoy safety and freedom. But really being the so-called evolved species how is it that we can't take peace, cooperation and unity over this divide that is ever so present.

What is this progress of building cities, expanding our scientific knowledge and building wealth if we can't stop ourselves from blowing each other up?

Yes, it's because of those soldiers that sacrificed their lives that we enjoy this freedom, but do the few have to die in order for the rest to have it?

If the price is peace, then what's the Prize?
