Allowing Multiple Citizenship Can be a step forward towards Peaceful World?

Most of the european countries, canada and some other American countries allow there citizens to keep multiple citizenship of different countries. In this global village that's a excellent step from that countries which allow their nationals to keep multiple nationalities, as the people of different countries have easy investment plans and easy ways to invest in other countries it reduces the risk of war because their people have investments in one another countries. And it will also promote cultural harmony and also a big step forward towards establishing global culture. We the people seeking for peaceful world ave a dream that one day there will be a dominating global culture in the world over regional culture. There will be global marriages global traditions global festivals.
  Some of the asian countries don't allow multiple citizenship to their citizens. In my opinion there should be also some reserved seats in parliaments or upper or governing houses of the countries & also in bureaucracy for those people who have multiple nationality, because they can think for any matter in better way, they will keep benefits for both sides while making decisions. In this way allowing and making easy multiple citizenship can be a good step forward towards a peaceful world.
