The Mumbai attacks originated in Pakistan, and the relations between the two countries have been going downhill since then. There is a negative perception of Pakistan in India currently.
In good times, we have also welcomed Pakistani cricket teams, players (for IPL), singers, comedians, actors and common people. Things are different now.
ORIGINATED IN PAKISTAN??? WHAATTTT?? you know what they say...innocent until proven guilty. so i think india and its people should stop accusing pakistanis for their own mess.
