>The history has proven that a society that share the common goals can advance forward. While those comprised with self-proclaimed leaders never really manage to unite any large nations.

This sounds nice, but I'm having a hard time thinking of any large modern states that appear to be driven by a shared common goal.

If such states only existed in the past, then my feeling is that is a result of romanticizing the past having not lived it. Maybe in 50 years people will look back on these last two decades as a time when large parts of the western world 'came together' with the common goal of 'fighting terrorism'.
