WASHINGTON (Agencies) - The Pentagon on Thursday said no decision has yet been made on deployment of additional US troops in Afghanistan and it has been in close touch with Islamabad over the proposal, which, if actualised, would also help Pakistan in curbing cross-border militancy. Pentagon Press Secretary Geoff Morrell told a briefing that Secretary Defense Robert Gates is expected to give recommendation on the proposal to President Barack Obama, the new commander in chief in the coming days. He remarked the additional troops in Afghanistan will be a delicate plus-up because you have got to do it commensurate to the infrastructure that exists in austere Afghanistan, Army Gen David D McKiernan, who commands US forces in Afghanistan as well as NATO's International Security Assistance Force, has asked his bosses for a 30,000-troop increase, which effectively would double the US military contingent in Afghanistan. Citing contacts between the top Pakistani and American military leaders, he said the Pentagon is "in close communication with our partners in Pakistan" over the desire of US commanders on bolstering troop deployment in Afghanistan. "I don't think this is lost on anyone. But I would remind them, as I remind you, that no decision yet has been made on this. And so-but this certainly should not be viewed as any sort of threat to Pakistan. This should be viewed as a way to help them combat a problem in their midst as well. "I mean, they have complained about what they believe to be the fact that the border in the Northwest Territories, in the tribal areas, is too porous in both ways, in that militants and extremists are able to move freely back and forth, greater than either of us would like. And so that's why we are seeing much better cooperation in terms of border security between us, the Afghans and the Pakistan military. So I don't think they should view it as anything but a positive if this comes to be," he said in response to a question. Asked if India is going to play a greater role in Afghanistan, he said, India is a significant political and economic partner of the Afghan government but he was not aware of any plan for a more pronounced Indian role in that country. "I know there's a great deal of investment by India in Afghanistan. I think this is a country that is in desperate need of investment and, I'm sure, would welcome it from all corners of the earth. So, but I couldn't tell you that I have any knowledge of a game plan for India to play a more pronounced role in Afghanistan. Questioned about new details on the US exploring alternate supply lines to Afghanistan in view of troops build up plan, Morrell said attacks on some of the lines of communication from Pakistan into Afghanistan have 'not had an operational impact. "We, you know, keep large surpluses of supplies, materiel, weapon-ammunition and so forth. But we obviously do need to have supply lines coming into Afghanistan to sustain this fight. Not just us, by the way. The Afghan military needs it especially." "But we have-we don't put all our eggs in one basket, either. While our relationship with the Pakistani government and their assistance with these supply lines has been very good, we have also looked and are pursuing, and to some degree have, additional supply lines from the north as well. And I stress, supply lines. There are multiple avenues which we believe we are-we will have to supply troops in Afghanistan from the north as well." Morrell saw no prospects of India being considered an alternate supply route. I do not believe so, he replied when an Indian journalist asked if the US could try India as a route. PPI adds: Appreciating New Delhi's role in the rebuilding activities in Afghanistan, the Pentagon has identified India as a significant political partner of the Afghan government. "India is clearly a significant political partner of the Afghan government," the spokes man told reporters. After the fall of Taliban, India has been involved in reconstruction and development works in Afghanistan in a massive way. However, in response to another question Morrell said he does not have any knowledge of " a game plan for India to play more pronounced role in Afghanistan.
