Kathryn quoted Carl Sagan:
"Every thinking person fears nuclear war, and every technological nation plans for it. Everyone knows it's madness, and every country has an excuse."

I quote (possibly?) Air Force General Curtis LeMay:
"Peace through strength!"
When will human beings ever learn to trust each other? lol Tribalism is so deeply rooted in us as a race. It is in fact my very misgivings about human nature that makes me realize we must have a strong nuclear and conventional warfare deterrant. Bullies and killers (whether an individual or an entire nation) generally only respect strength and the potential of another to hurt or slay them.
But I do believe we need cultural exchanges, open dialogues, peace talks, economic ties, etc., to connect with each other's humanity, or else eventually massively unrestrained violence at the nuclear (or nanotech, biowarfare, etc.) level may erupt.
I don't want humanity colonizing the galaxy while we are still so divided. A repeat of the 15th, 16th and 17th century (the age of exploration and colonization write large in space) might not be such a good thing...
