Peace in the world could be possible if we all live and think as humans rather than religion, Country boundary, color and status. If you look around the wold peace has been destroyed just for the sack of money, minerals or for the peace of land. If we think that all humans are equal and we have to respect other's religion and rights then peace is sure everywhere. Prosperity must come and no country and nation will need atomic power. Just focus what we have and what we can get from our resources. Not to get other nation's resources. And through hardworking every thing is possible not by fight.
I hope you will agree with me. Let me know about your idea.....
