WASHINGTON - As Pakistan moves towards stability following the recent political crisis, a top Advisor to the US Central Command (Centcom) warned that the country could collapse within six months. David Kilcullen, an Australian anthropologist who advises Centcom commander General David Petraeus on the war on terror, expressed serious concern over the rising extremism in Pakistan, saying that it could prove detrimental to the world peace. "Pakistan has 173 million people, 100 nuclear weapons, an army bigger than the US Army, and Al-Qaeda headquarters sitting right there in the two-thirds of the country that the government doesn't control," he said in an interview to The Washington Post published on Sunday. "The Pakistani military and police and intelligence service don't follow the civilian government; they are essentially a rogue state within a state. We're now reaching the point where within one to six months we could see the collapse of the Pakistani state, also because of the global financial crisis, which just exacerbates all these problems. . . . The collapse of Pakistan, Al-Qaeda acquiring nuclear weapons, an extremist takeover - that would dwarf everything we've seen in the war on terror today." Kilcullen said the US considered Pakistan as the 'central front' in the US-led 'war on terror', and he urged US policy-makers to focus their attention on the country as a failure there could have devastating consequences for the entire international community. Kilcullen, who advises governments on militancy throughout the West, disagreed with the suggestion that it was important to kill or capture Osama bin laden. "Scenario one is, American commandos shoot their way into some valley in Pakistan and kill Osama. That doesn't end the war on terror; it makes Osama a martyr. But here's scenario two: Imagine that a tribal raiding party captures Osama bin Laden, puts him on television and says, 'You are a traitor to Islam and you have killed more Muslims than you have killed infidels, and we're now going to deal with you.' They could either then try and execute the guy in accordance with their own laws or hand him over to the International Criminal Court. If that happened, that would be the end of the Al-Qaeda myth."
