Maddy, DG ISI isn't going, a Director level ISI rep is leaving for India!
Even that is better than before. No previous Pakistani government has ever reacted to an attack on India, particularly one that India blamed prominently on Pakistan, by quickly sending a senior intelligence official.
While the nationalistic feeling would be to react to India's insult, Gilani has essentially ignored it and is actually doing something to help.
Of course, the same watchouts remain. If India use this to continue to lay false accusations on ISI, rather than avail themselves of ISI's assistance, this is an opportunity lost.
Not only that but internationally this help to bolster Pakistan's argument that it is not involved. Actually giving help in this way speaks much louser than words.
