NEW DELHI (Agencies) Describing Pakistan and China as 'two major irritants' for Indias security, Indian Army Chief General VK Singh on Friday said the armed forces should ensure the country has a 'substantial conventional war capability to fight in a nuclear scenario. We have two major irritants. One, there is a problem of governance in Pakistan where terror outfits receive support and where internal situation is not very good. And, therefore, it can have a fallout in terms of how these things impact India. Till the time the terrorist infrastructure remains intact on the other side, we have something to worry, he said inaugurating a seminar on 'Indian Army: Emerging Roles and Tasks in New Delhi. He also referred to the threat posed by China, which was rising both economically and militarily. Although we have a very stable border, yet we have a border dispute. And, therefore, the intentions need to be looked at along with this additional capability that is coming out, he said. General Singh said, It impacts the way we will task our army and the role that we will give to it so that it can do the task that the nation wants. So, with this, lets also see what are some of the threats that we face or the challenges that we have. He said, Even though we have a stable border with China, we cannot take chances. He told the seminar that an all-out conventional war with China was 'not certain, but skirmishes were 'certainly possible. We must have a substantial conventional war-fighting capabilities with the ability to fight in a nuclear scenario, he stressed. Singhs remarks come close on the heels of Defence Minister AK Antony stating that China was exhibiting 'assertiveness in its military posturing in the region and asked the armed forces to remain vigilant to counter any threat. Though the Indian Army Chief did not name the Maoists, Singh said 'internal dissent and insurgencies in Occupied Kashmir and the North East were the other threats that needed attention.
