Why Do We Have War?

I saw this on FB a day ago and wanted to share, because it is dead-on true.

The US economy is based on killing people. War is big business, and people let themselves be brainwashed with patriotic bullshit to support it. It's sad really, and what's sadder still is this country so likes to think of itself as a "Christian Nation". Somehow, I don't think Christ would agree.
