Sad Thanksgiving India

While a lot of us were celebrating Thanksgiving day and enjoyed the happiness with friends and family, that was a black and sad Thanksgiving day in India. I believe a lot of us have been watching the news and shocked by the terror attacks in Mumbai for the last 24 hours...Mumbai became a bleeding city in one night.
Why why why???
Why those terrorists killed so many innocent people? What they are fighting for? Why every one of us in the world, in the world of human, can not just lead our own life peacefully, respect each other believe and religion, respect each other living life, respect each other life style. lead our own life in our own country, don't too much bother about others, will this world be more peaceful?
