PAKISTANIS are not the only people whom President Clintons televised address from Islamabad has left shell-shocked. Most Indians also feel the same. If the predominant feeling in Pakistan is dismay, in India its anxiety. Even as the realisation dawns in New Delhi that the US has really changed its subcontinent policy, people have begun wondering whether it may not be confined to President Clinton, and therefore subject to being reversed when he leaves office next February. Pakistan fervently hopes that is so. As outspoken academic Shireen Mazari said on Pakistan TV before Clintons broadcast that he seemed to have been "de-educated" during his India visit. Indians too fear that this may indeed be so, and that the next president will be banefully influenced by the state department, the Pentagon, and the powerful Pakistan lobby - which have been so effective.
