PARIS (Reuters/AFP) President Asif Ali Zardari warned that the international community was losing the war against the Taliban in Afghanistan, according to an interview published on Tuesday. Zardari said the US and NATO-led coalition forces had underestimated the situation on the ground in Afghanistan. I believe that the international community, which Pakistan belongs to, is in the process of losing the war against the Taliban, he told Le Monde newspaper. And that is, above all, because we have lost the battle for hearts and minds. His comments came after military documents leaked to the media pointed to alleged support by Pakistani officials for the Taliban. Zardari has insisted that Pakistan is committed to fighting militants in the region. Since the US-led invasion of Afghanistan drove them from power in 2003, the Taliban have waged a fierce fight against international forces. I think they have no chance of regaining power, but their grip is strengthening, Zardari said of the hardline movement. Britains Prime Minister David Cameron angered Zardari by saying last week that Pakistan must not look both ways in secretly promoting violent extremism while pretending to seek regional stability. Zardari vowed to tackle the allegations head on when he meets Cameron on Friday at the British leaders country retreat outside London. The war against terrorism must unite us and not oppose us, Zardari told Le Monde. I will explain face to face that it is my country that is paying the highest price in human life for this war. Zardari was due to head to London later on Tuesday after two days of meetings with French leaders. On the last day of a visit to France, Zardari said such fears would undermine international efforts against terrorism. It is unfortunate that certain individuals continue to express doubts and fears about our determination to fight militants to the end, Zardari was quoted as saying in a statement. Such fears will only weaken the international effort to fight militants and extremists, said the statement, issued by Zardaris office before he met Frances foreign minister. Pakistanis were disappointed by Camerons comments especially as he said them in India and for this reason it was even more important for the president to visit Britain to address this issue, the statement said. Zardari said Pakistan was taking control in the war against terrorism and that no other country had paid as big as price as his. French officials said on Monday that President Nicolas Sarkozy was conciliatory in talks with Zardari, which did not touch on either the leaked military documents, or Camerons comments. Protesters in Karachi burnt an effigy of Cameron. Pakistans spy chief called off a trip to Britain in protest, but Zardari did not cancel his visit. Before heading to Britain late Tuesday, Zardari met French Foreign Minister Bernard Kouchner for a working lunch expected to address European humanitarian aid in the wake of this weeks deadly Pakistani floods. In his talks with Sarkozy, Zardari called for massive international assistance to cope with the floods, the statement said. After his official schedule, Zardari was to make a brief private visit to Normandy in northern France where his family owns a chateau.
