All countries should merge and live as one world. So that every human being can live happily. In this world no ones life is permanent, an individual comes with empty hand and goes with empty, as long as an individual lives; should live happily without any problem.
At present some are living very happy and some are suffering like anything. I don't know who has given the rights to divide the countries.
Think practically and logiclly, anyhow every country is taking help with other country in some areas, then why can't they live together.
