ISLAMABAD (Reuters) The Pakistan Army is unlikely to change its assessment of the threat from India despite heavy demands on its troops to provide flood relief while also fighting militants, a senior security official said. The Wall Street Journal said this month Pakistans Inter-Services Intelligence (ISI) agency had decided - for the first time in the countrys history - that militants had overtaken India as the greatest threat to national security. But the security official suggested this was a misinterpretation of the stance of the Pakistan Army, which views the threat from militants and India in very different ways, rather than comparing them against each other. These are two mutually exclusive threats. The magnitude, the type, is quite different. One is an internal threat which is insidious, difficult to quantify. It is a clear and present danger. This is a very serious threat, he said. The other is a conventional threat. What has India done, politically and militarily, for this threat to have been reduced? Another official said the threat from India had if anything increased into both a conventional and unconventional threat, as it used its presence in Afghanistan to support those fighting against the Pakistani state in its western border regions. India denies accusations by Islamabad that it backs rebels in Balochistan. With flooding which has uprooted some 6 million people further destabilising a country already battling militants, the WSJ report raised the possibility the Pakistan Army might revise its assessment of the threat from its much bigger neighbour. The DGMOs of the two countries talk by phone once a week, mainly to clear up misunderstandings over any ceasefire violations on the Line of Control. But the security official said that Pakistans military deployment was based on its assessment of Indias potential offensive strength. The configuration of any defence force is based on enemys capabilities and not intentions, he said. For Pakistan to drop its guard against India would require progress on political disputes, including over Kashmir, officials say. While Pakistan fights militants on its western border with Afghanistan, it remains wary of sudden Indian retaliation should there be another Mumbai-style attack on India. This enforced attention to the western border has made the Pakistan Army reassess its priorities, said western military analyst Brian Cloughley, an expert on the Pakistan Army. But it still does not wish to drop its guard to the east, especially as the there is still the threat of a swift and dramatic attack if a terrorist outrage in India is determined by India to have been planned in Pakistan. Pakistan has said it cannot guarantee there will be no more attacks on India, arguing that it too is a victim of bombings.
