Well, at least one can say, they tried. The human endeavor for peace. Reminds me of what D'Lenn said of humans in the TV series Babylon 5

"Were one race were to make a large station like this, it's likely to only be used by that race, and few others would ever live there, except as guests. But yet, humans build a place like this, and it becomes a home for many."
"Everywhere humans go, they create communities. It is a wondrous gift, and a massive responsibility"
