Need for pro-democracy and pro-immigration stance

Many countries in the world hates the word immigration.The only
superpower in the world USA has become superpowers because of their
liberal immigration policies.The land of the aliens is superior to
other countries because it is a land of the melting point.I was
remined of a letter in the guardian by someone ,who after the
Hurricane Katrina, said that if the USA fails the world fails.They
often solve their own problems by their own ways.We saw the
mismanagement and chaos of the the earlier efforts but the later
coverage by BBC ended with the comment "finally the superpower is
acting like one".
Meanwhile the nazi countries like Denmark,Norway and Germany who
inhibits immigrations.Treat them like dogs,and affectively employ nazi
tactics on foreign people(except those from america of course,coz they
americans have money) are living happily.For example even if you marry
somebody from Denmark,you can't get a Danish passport provided you are
not an american.Nazism at its best.When I was in Europe last year, I
saw the fear of the people towards people from Asia.They think that
somehow Asians could get their jobs.They hate Asians,blacks and
attacks on Turkisk people in Germany is almost upto the full Nazi
level.
My 2 cents
