Pakistan's army will finish its offensive against Taleban militants in the Swat valley and ensure peace, Prime Minister Yusuf Raza Gilani said on Monday as he rallied the support of political parties. “The operation against the terrorists is progressing very successfully and those who destroyed the peace of the nation are fleeing in disguise,” Gilani said in an opening address to an all-parties conference on the fighting. “Troops will remain in the region until peace is ensured and all the displaced people return home,” he said. “The displaced men, women and children should not feel alone. We won't leave any stone unturned in providing them help and protection,” Gilani said. “A victory in the fight against terrorism is in fact a guarantee for the security and protection of our coming generations,” he said. Gilani called for political parties to play a constructive role. “I'm well aware that army action is not a durable solution to any problem,” Gilani said. “Unless the people and political parties come out to play their genuine role for the solution to an issue, no durable solution can be found,” he said. On the contrary, the Pakistani Taleban have vowed to resist military advances in the northwest's Swat Valley until their “last breath,” while the government Monday sought to bolster political support for the offensive ahead of potentially bloody urban battles.
