So India and Pakistan will play each other again on Indian soil, this time in the World Twenty20 cricket tournament.

Saturday's match will take place in Kolkata (Calcutta), having had to be shifted from picturesque Dharamsala because the chief minister of Himachal Pradesh state felt the families of Indian soldiers from his state would not welcome a game with the "enemy".

The Pakistanis nearly did not come at all, out of fear for their security.

The question of whether, amidst all the strife that besets the two countries' cricketing relations, a mere sport can bring them together, is at one level easy to answer: No.

Sport can sublimate many emotions, but it cannot be a substitute for geopolitics. Cricket can be an instrument for diplomacy, not an alternative to it.

After all, six decades of cricketing ties have done little to promote good relations between the two antagonists.
