I would love to see the world unite, but that will probably never happen. It's in the nature of human beings to fight over things.
Because of religion
Because politics
Because of prejudice
Because of language barriers and misunderstandings
Because of the greed of certain individuals, there’s too much profit in conflict to allow it to end
Because humans are just intelligent animals, still driven by emotion and instinct, not logic, we still follow the leader, even if that leader is a lying sociopath.
It is true. If the human nature was not what is, we would have already reached greater heights of success. But I am an optimist and I have to believe that some day in the future, we might just all change.
"Because of the greed of certain individuals, there’s too much profit in conflict to allow it to end"
we could easily fix that with communism
