ALL that Indians and Pakistanis ever wanted from their leaders was that they silence the guns along their needlessly tense borders and to go back to a ceasefire, which their forebears had worked out in a moment of sagacity in 2003. All that was needed was for India and Pakistan to hold irreversible talks at any desperate level, and if nothing came out of them, to continue talking. One reason you and I are alive today may lie in the fact that at the height of their nuclear brinkmanship Kennedy and Khrushchev never shut down the lines of communication with each other.
