In view of the very apt letter by Mr Muhammad Yaqoob Bhatti, it is imperative thatPakistans contingency reserves be increased. Building Kalabagh dam would be the quickest way of improving upon the very precarious 30 days reserves that we have, as against 120 and 900 days forIndiaandUSArespectively. Not doing so would leave us at the mercy ofIndias designs. KHURSHID ANWER, Lahore, June 8.
