WASHINGTON - Pakistan has planned more actions in the coming days against the extremists who challenge the new government militarily as its pursues its offensive in the Khyber agency, Ambassador Husain Haqqani has said.  In an interview with The Washington Times, he said the additional measures in the Afghan border area will demonstrate to the world the elected government's commitment to fighting the Taliban and other extremist groups. Haqqani said the new plan would have far greater legitimacy and effectiveness because it had been drafted and approved by a democratically elected government. The offensive against a warlord near Peshawar was just an example of what is in store for any extremists, the Pakistan ambassador added. "The message [in Saturday's strike against a Taliban-allied militant group led by Mangal Bagh] is that this is going to happen to anyone who does the same thing," said Haqqani, who said government forces would chase down  Bagh in the remote corner of Pakistan's tribal regions where he has fled. Bagh and his force of tribal militants sparked the weekend attack by encroaching into positions around Peshawar and seeking to impose extreme Islamic practices on the inhabitants. The group was quickly routed by Frontier Corps troops backed with tanks and helicopters, sending Mr. Bagh fleeing for safety. The ambassador, a former scholar and journalist well known in Washington's think-tank community, said the new government may take longer to reach a decision than the previous government, but that its policies were more likely to stick. "There's a difference between a drift and a transition," Mr. Haqqani stated. "Making decisions is a slightly lengthier process than it was when one person could make it. But the upside to it is that once the decision is made, it has national support and consensus," he argued.   Haqqani also pointed out shortcomings in U.S. policy toward the region in the days after the Sept. 11 attacks, saying there has been a "complete failure" of American public diplomacy in Pakistan and the Muslim world to explain and defend U.S. objectives and interests in the global war on terrorism. U.S. military leaders and Afghan officials have complained that militant cross-border strikes surged after past efforts at compromise. The ambassador said said the first operation, launched in the Khyber tribal area Saturday, had achieved its "basic objective" by destroying bases and safe houses belonging to Bagh in the village of Bara, about 10 miles outside Peshawar. The militant leader was not caught. "The message is, 'This is going to happen to anyone who tries to do this kind of thing,'" the ambassador said. "The Pakistani military has been given the job and task of ensuring that there will be no flow of Taliban fighters from Pakistan into Afghanistan ." He also said American diplomats showed "greater courage" serving behind the Iron Curtain during the Cold War than they do today serving in countries with a high threat of terrorism. American ambassadors also serve too little time in Pakistan to really understand the complexities of his country. He acknowledged that security threats are so great in Pakistan that American diplomats do not bring their families with them during their tour there. "There were security problems during the Cold War ... but American diplomats showed greater courage," he said. Haqqani added that even during the Vietnam War, "diplomats stayed" until the fall of Saigon. "Now there's this problem because of terrorism," he said, explaining that U.S. diplomats rarely stray far from the U.S. Embassy. "They don't go out very much .... They stay in the capital .... There is a very quick rotation."
