WASHINGTON (Online) - US President Barack Obama has said his administration - seeking a viable way forward in conflict-hit Afghanistan - wants an effective partnership with Pakistan that works towards achieving peace and stability in the region. In an interview with ABC news channel, the US president stressed that the Afghans must share the burden of their own security and made it clear that Washington is not looking at an indefinite stay in Afghanistan. President Obama said in the interview that as commander-in-chief he has obligation to make sure that whatever investments Washington makes are leading to a safer United States, (that they) are sustainable. ....that we have a strategy to make sure that Afghans are carrying the burden of their own security, that we have an effective partnership with Pakistan that is working to achieve our goals in the entire region and that we are not working at cross purposes, that issues of corruption are dealt with, that we are identifying not just a national government in Kabul, but provincial government actors that have legitimacy ... right now, he stated. So, there are a whole host of those questions that we have worked through systematically. I have gained confidence that theres not an important question out there that has not been asked and that we havent asked-that we havent answered to the best of our abilities, he said. And as a consequence of the process that we have gone to, I feel much more confident that when I issue my orders, that not only do we have a better prospect of success and we are serving our men and women in uniform well, but that we are not also looking at an indefinite stay where we have bought, essentially, a permanent protectorate of Afghanistan that I think would be unsustainable. We are trying to control a fierce Taliban insurgency in Afghanistan while Pakistan is fighting militants on its side of the border - considered one of the most difficult terrains in the world, he added.
