It has nothing to do with cricket. India has already done some crazy stuff and I don't want to see more. I am a fan of Indian cricket team. If India abandon the match, probably I will never watch Indian cricket match anymore. Politics should be stay out of sports. In fact, sport is one of the way to increase friendship/brotherhoodness among countries.
I dont think India will pull out of this match, if you see matches between these two Asian rivals generate huge amount of money for all the parties, and none will want to loose that. Im not sure why you would stop watching matches if they decided to skip it, if their government orders they will have to obey it. In the past both countries have interacted via cricket matches, so itll be interesting if they can set aside their differences for the sport.
It is true that it will be government decisions and the board has clearly the doubts that they will obey the orders what the government will decide and their will be no questions asked on this. So things will clear out in coming time regarding it. Also Ganguly and Harbhajan has clearly opposed the match which will be played.
