One year ago, I asked whether then President-elect Barack Obama's plans for Afghanistan still made sense after the Mumbai attacks torpedoed hopes of a regional settlement involving Pakistan and India. The argument, much touted during Obama's election campaign, was that a peace deal with India would convince Pakistan to turn decisively on Islamist militants, thereby bolstering the United States flagging campaign in Afghanistan.
As I wrote at the time, it had always been an ambitious plan to convince India and Pakistan to put behind them 60 years of bitter struggle over Kashmir as part of a regional solution to many complex problems in Afghanistan. Had the Mumbai attacks pushed it out of reach? And if so, what was the fall-back plan?
One year on, there is as yet still no sign of a fall-back plan for Afghanistan and the tense relationship between India and Pakistan remains the elusive piece of the jigsaw.
After some attempts at peace-making which culminated in a meeting between the leaders of India and Pakistan in Sharm el-Sheikh in Egypt in July, and despite Prime Minister Manmohan Singh's own determination to try to repair relations, the two countries have descended into mutual recrimination.
India accuses Pakistan of failing to take enough action against the Lashkar-e-Taiba militant group it blames for Mumbai and which analysts believe is still in a position to launch fresh attacks, and refuses to reopen formal peace talks broken off after the three-day assault. Pakistan has put seven men on trial over the attacks but has refused to arrest the group's founder Hafiz Saeed nor, analysts say, to dismantle the infrastructure of an organisation whose original role was to fight India in Kashmir. It says it wants to resume talks with India.
