WASHINGTON (Online) - The top US military official has again warned that the militant outfits are seeking global reach and the Afghan-Pak border area remains the 'epicentre of terrorism. The reason were focused on Afghanistan and Pakistan is that living in that border area are the terrorists from various organisations and it has become the epicentre of terrorism in the world, Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff, said in a speech at the Texas A&M University. Several of those organisations, in addition to Al-Qaeda, now have global aspirations and are moving to a point of having global operational capacity. And they threaten us very specifically - the United States, Western interests, our European friends, Mullen said. According to Mullen, keeping the pressure on the terrorist organisations now is critical, as he listed several measures including improving governance, education and economics in countries whose young people are becoming part of such groups, to tackle the challenge. I dont think we can kill our way through this. I think those conditions have to change and thats a long-term challenge. Thats not going to happen overnight. But together with other countries - responsible global powers - we can make significant progress over time. Thats the long-term answer, he said.
