I don't understand this thread? Are you talking about people's favourite countries? or top countries that Pakistan has mutual interests with?
anyways my top five countries in no specific order are
1) Greece (The beauty of the human mind, free thought, liberalism and the concept of democracy and reasoning started here, i would love to travel to Greece, i am planning a trip to Croatia next year and will definitely visit Athens, I also enjoyed Greek mythology as a kid)
2) Egypt (How can one forget this absolutely amazing land, I would cut my arm to see King Ramses Tomb, The Pyramid of Giza, The Sphinx and so much more. The only problem is there are to many tourists, i would preferably go there at a time early morning at dawn when no one is around to truely appreciate the wonders that humanity is capable of and take shots from a tripod. My dream would be to nonetheless go inside and top of Giza, would have to take permission from Zawi Hawas which would be denyed on the spot unless i was a journalist.
3) United States of America There are moments when I hate it and there are moments where i Love it, I love what the United states was founded upon. Franklin, Washington, John Adams and the best Jefferson all of whom were deists and extraordinary people. America was built and founded by people who wanted to escape aristocracies, monarchy's and the very clutches of religion that plagued Europe for over a thousand years. I would love to visit the Jefferson memorial, library of congress, The washington monument, the natural museum of history and technology. There is so much to do its quiet overwhelming. It is afterall the land of Ideas and has a great entrepreneurial spirit, if only some would stop thinking that the Sun rises and sets in America and the neo conservatives nutjobs shut up.
4) Japan One of the best countries i find which blends culture with modernity in probably the most sophisticated manner. For me Japan represents technology, how can anyone hate a country that makes great cars, the best dam electronics in the world, has sushi, anime's, videogames and crazy wierd horror films, and the awesome Mount Fuji, you just can't go wrong with Japan.
5) Ecuador (Galapogas Islands) The worlds craziest species live here, the most vibrant wildlife one can possibly imagine, Darwin's brilliance and wealth of information, education came from this exotic island. In this unique location, so abundant with fascinating science stories one can only see and look at how awesome and wonderful our planet is.
