OUR leaders refuse to learn from past mistakes. When V.P. Singh formed the National Front government in 1989, he allocated the coveted Home Ministry portfolio to Mufti Mohammad Syed. V.P. Singh, the great champion of secularism, obviously believed that a representative of the minorities in the sensitive ministry would send out the right signals. Never mind if the biggest problem facing the country was Kashmir, and Mufti as a past player in the state's politics was particularly vulnerable on that count. It was hardly surprising therefore that the ministry's handling of Kashmir during the National Front regime bordered on the disastrous.
