In an even more direct indictment of Pakistan's ISI spy service over its links with terrorist groups, federal prosecutors in the US are reportedly set to name five Pakistanis, including a serving ISI officer, in the trial of an accused in the 2008 Mumbai terror attacks. Add to that the revelation that US authorities, in recommendations to interrogators at Guantanamo Bay , list the ISI alongside groups accused of terrorism, and it seems virtually an official declaration of what has been common knowledge.But the quandary is that there has been close collaboration between the CIA and the ISI in the past, and the US still needs the ISI and the Pakistan army as it deals with Afghanistan. The moot point now is whether a hitherto unprecedented level of pressure can be brought to bear on the Pakistan army to move against groups it has so far been sheltering, and whether sections in the ISI and the army who remain wedded to the policy of using terror groups for strategic objectives can be excised.The perverse logic of a militarised foreign and strategic policy has so pervaded the Pak army that it may not just be a case of a problematic section within its institutions. So entrenched is that policy that the Pakistan army is unwilling to move against terror groups without making any discriminations between them, despite some of these groups having unleashed a campaign that has taken the lives of over 30,000 Pakistanis in the last few years.It's a truism that we can't choose our neighbours. And things going from bad to worse in Pakistan will spell trouble for the region. There has to be a judicious mix of engagement and requisite pressure India and the wider international community must employ while dealing with the Pakistani establishment. The latter needs to realise the cynical search for 'strategic depth' means the inevitability of terror groups it has nurtured turning against it, and not just deeply distrustful neighbours. Changing that will take a multi-faceted effort on India's part. And it is also likely to be a long haul. But seeking long-term stability and peace in the region demands that India stay the course.
