I was thinking about how we (USA) are always in continuous (ghost) wars and never try to negotiate for peace, to my knowledge.
How would a peaceful world look like?
One country and one languague or would a world power have to forcibly join everyone together?
You do have a great point. All countries would have to cone to an agreement on fundamental laws that would govern the world.
There are many forms of governing and often that form is result of local environment and culture. Flow of wealth through the society being an important part.
