Thank you for posting this. I'm one of the Peace Fence organizers, and the creator of the panel, "Wars are based on lies we tell ourselves about what is possible." Let me give you the entire poem from which I took this:
Did you both examine each and every option?
Sit down and talk until you were out of words?
Consider the dire cost in blood and treasure?
Envision survivors grief, the orphaned children?
Did you bother to recall human history? Wars are based
On lies we tell ourselves about what is possible.
(By Nancy Parker)
The shape of the poem's 6 lines forms the I Ching symbol for the "Army."
