khorasan, which is a region, of course, encompassing much more than afghanistan. parts of south asia, iran, parts of china, pakistan, pakistan's intel service, the isi has been heavily involved with the taliban. do you worry about broader regional instability? >> absolutely. and i worry most about how this will impact india-pakistan relations. we are talking about two nuclear arm countries that have already fought three wars in the past 70 years. and have had major crises in just the last few years. and so, terrorist groups that attack india will now be emboldened. they'll be able to train and -- and regroup inside afghanistan. these are groups which have brought india and pakistan to the brink of war in the past. so there are very wide repercussions for the terror safe haven that we will see in afghanistan.
