I still prefer living in a world of countries and boundries.  For this is the best way to treat everyone  fairly.  For we all know that every country has their own government depend on the majority wants of people.  There a lot of people now transfer to other country when they can't live with the way they country do. So there is a wide choice for everyone. So,  as to think,  it's better to be in a world of countries only.  😊
