WASHINGTON - Former President Pervez Musharraf, who often had tense relationship with President Hamid Karzai, Wednesday criticized as "preposterous" the Afghan leader's statement that his county would stand by Pakistan in case the United States attacked Pakistan. Responding to a question about Karzai's remarks, Musharraf thanked, with a touch of sarcasm, the Afghan leader for giving a pro-Pakistan statement, but called the idea of war between the US and Pakistan 'ridiculous and preposterous'. "Karzai's statement - first of all, let me thank him, for the first time, giving a pro-Pakistan statement. But ... the statement that he will support Pakistan against United States is most preposterous, I would say. I find this idea itself very preposterous," Musharraf said at the end of speech at the Carnegie Endowment for International Peace, a Washington-based think-tank. "Is he visualizing some kind of war between the United States and Pakistan? It's ridiculous and preposterous. The thought of it is preposterous. So therefore, I wouldn't like to even answer this; I find this a very, very strange idea. Who has propounded this idea? And God forbid, I mean, this can never happen. So why comment?" he added. Musharraf also urged Karzai to focus on taking on Afghan militant groups instead of pledging his country's support to Pakistan. "And thank you very much. Please look after the Taliban and al-Qaeda; that is enough. Don't support Pakistan. Pakistan will look after itself," Musharraf added. Since Karzai made that statement, his spokesman has been trying to explain the comments and has even suggested they were misinterpreted by the Pakistani media.
