Its politically the right thing to do.
If a country you believe trains terrorists and sends them over to blow up one of your prized cities and then wants to play cricket with you, would you do it?
Sending the players over to such a volatile nation especially at a time like this would be asking for trouble. Imagine if the next headline you read would say "Indian Cricket Team die in Pakistani bomb blasts....Pakistan denies any involvement"
This is about more than cricket and we should stop being selfish just because we want to see the games.
India is still being far too diplomatic, they should have stopped ALL activities with Pakistan as soon as they found out where young Ajmal was from.
This should continue until Pakistani society condemns their army and ISI for sponsoring terror against India and stops the killing of innocent lives. The usual "Pakistan is also a victim" is getting tired. It is their creation and they should do something about it or I predict more than cricket will be taken away from them.
What'll be next India's support for rising Pakistani films, filmstars and singers?
