HONG KONG (AFP) Former president Pervez Musharraf said Wednesday he would soon launch a new party, touting his support among the Facebook generation as he vowed to remake the nations turbulent politics. The retired general also accused Afghan President Hamid Karzai of lacking legitimacy but urged the West to stay the course against the Taliban or risk destabilising the region still further. Im going to declare a party on October 1... We have to bring about a new political culture in Pakistan, he told reporters in Hong Kong after addressing an annual investors forum organised by the CLSA brokerage. The 67-year-old Musharraf, who lives in self-imposed exile in London, shrugged off the threat of possible legal action arising from his years of military rule of Pakistan. There are elements opposed to me, political elements, and they are the ones who engineer these cases. One has to face that. Im very confident nothing can happen (on his eventual return home), he said. Musharraf, who plans to stand for parliament at the next general election in 2013, did not say where he would launch his new party - called the All Pakistan Muslim League. Reports say the October 1 event is slated for London, and Musharraf has proclaimed his belief that he could become president again. Musharraf said that more than 80 percent of the 295,000-plus followers of his Facebook page were aged between 18 and 34. Therefore I know that it is the youth who are yearning for change. After the September 11, 2001 attacks, Musharraf made Pakistan a key ally of then US president George W Bush in the war on terror, but faced a resurgence of militancy in the tribal northwest near Afghanistan. He had a dismal relationship with Karzai, who regained power last year in an election that was widely decried as fraudulent. There must be a legitimate government in Afghanistan... He does not have that legitimacy, Musharraf told the CLSA forum. In contrast, the former military leader heaped praise on US General David Petraeus, calling the head of foreign forces in Afghanistan a great commander. But with US President Barack Obama planning a troop drawdown from mid-2011, Musharraf warned that abandoning Afghanistan would be playing into the hands of the Taliban and Al-Qaeda, and said quitting is not an option. The whole world is against the Taliban. So why cant we win? We can win and will win. But we will suffer casualties, he said. No one is analysing the effect of abandoning the region on Afghanistan, Pakistan and the world.
