If the Earth is not united on the first attempt, try and try again until it is.
Maybe a smaller goal is required, at first.
(More will realize their lunacy and voluntarily change their reasoning later).
As they like to say, “build it and they will come”.
So as a compromise, how about splitting the Earth in two?
A insane side, to maintain the way for how things are ran now, where people stay rooted in their histories to maintain borders of separation, competing and warring against each other, to personally profit on ideas, talents, and capabilities – basically to rape each other in a land of total prostitution. But because it is still survival of only the fittest and most cunning, leaving the weakest to suffer and die, it is more like a land of barbarism over ran by ignorant cavemen clumsily stumbling about.
And a sane side, where matured and civil Human beings, citizens of the Planet Earth, can exist now and gather to live. The better side of a planet, engineered for communicating, sharing, and cooperating. A land where each minor voluntary contribution adds to the organized whole for there is no need to extort since Human beings are all equal and the only thing holding any value is Life. Everything else are just necessities of which we have a capability of providing and freely should. The reason why it is a sane side is because these individuals realized that they are all mothers and fathers, all sons and daughters, all fortunate to be alive, the last surviving members of the Human race, and sharing a life-supporting planet, Star, and Universe today. It makes sense that they would need to make sure every single Life is cared for and today provided the very best imagined in order to ensure a bright and long future for the entire Human race.
Trick or treat? Which side of the planet would you live on? Which side would you raise a child on?
Uniting the world and bringing peace and convenience to every Life is common sense.
So if at first you don’t succeed, try and try again.
