WASHINGTON - President Barack Obama has praised Pakistan for its anti-Taliban military operations and urged the international community to help the country deal with the displaced persons in ways that deter them from becoming sympathizers of extremists. Pakistans military has stepped up in a way we have not seen, Obama said in an interview broadcast on ABCs Nightline programme Thursday. I mean, they are engaged in serious fighting of al-Qaeda allies in that region and are trying to reassert control into areas that have become lawless. While lauding the Pakistani offensive, Obama also noted that here were downsides to that. Youre seeing the displacement of a lot of people in those battle zones. And Im very worried that we, as an international community, are helping Pakistan to deal with those people whove been displaced because we dont want that to be a new recruitment tool for radicals saying that, you know, youve been chased out of your home because of Pakistan, which that kind of propaganda I think is something that we have to be careful about, he said. I think that the Pakistani government in the past has been has tried to take the tiger by the tail and use in some cases, you know, militants to their advantage strategically. And I think they now realise that that was a mistake and my hope is that were going to see them continue to take seriously the threat not simply to us, but, probably more acutely, the threat to Pakistan. Replying to a question about the Afghan war, Obama said hes uncomfortable using the word victory to describe the United States goal in that strife-torn country. He said the US fight there is against broader terrorism and not a nation. Obama said that the fight is not going to end with a country surrendering to the United States. The president said the fight is against al-Qaeda and other terrorist organisations so that they cannot attack the country. You know, were not dealing with nation states at this point. Were concerned with al-Qaeda and the Taliban, al-Qaedas allies. So when you have a non-state actor, a shadowy operation like al-Qaeda, our goal is to make sure they cant attack the United States, the president said. Now I think thats going to require constant vigilance. But with respect to Afghanistan, what that means is - or Pakistan, for that matter. What that means is that they cannot set up permanent bases and train people from which to launch attacks. And we are confident that if we are assisting the Afghan people and improving their security situation, stabilising their government, providing help on economic development so they have alternatives to the heroin trade that is now flourishing. If on the Pakistani side, we are helping to stabilise the northwest provinces and giving them assistance and providing people a good livelihood - those things will continue to contract the ability of al-Qaeda to operate. And that is absolutely critical, Obama added. When Obama delivered a speech in March about his strategy on Afghanistan and Pakistan, he did not use the word victory. Obama spoke with ABCs Nightline while travelling to Ohio and Illinois.
