But their overtures have been largely rejected -- until now.
On January 7, the Afghan government announced that a former Taliban commander who switched sides before a battle last month to secure Musa Qala, a Taliban-held southern town, had been named the government's top official there.
By making a deal with Mullah Abdul Salaam, the new district chief of Musa Qala, the government appears to have taken a key step toward changing the face of Afghan politics. And Kabul is hoping the move will encourage more defections by moderate Taliban.
From his headquarters in Musa Qala today, Mullah Abdul Salaam told RFE/RL's Radio Free Afghanistan that his appointment is already fostering reconciliation between the government and moderate Taliban.
"There were many problems before. There was no trust before. There was no one you could trust," he said. "People didn't know whom to contact. Now they are talking with me. They give me assurance and I give them assurances. There were many problems before. There was no trust before."
Mullah Abdul Salaam was once the Taliban's governor in the southern Afghan province of Oruzgan -- the birthplace of the Taliban's spiritual leader, Mullah Omar, as well as Karzai.
Now, the powerful local commander brings some 300 militia fighters to the side of the Afghan government in a strategic part of Helmand Province. More importantly, his allegiance to Kabul helps extend the central government's authority into an area seen as a bastion of popular support for the Taliban.
Christopher Langton, who studies Afghanistan at London's International Institute For Strategic Studies, says it is a particularly important area for President Karzai to stabilize.
"If it is stabilized, all sorts of follow-on could occur in other parts of the country when people see a successful outcome [in Helmand Province]," Langton says.
Langton says the stabilization of Musa Qala and the fertile farmland of the nearby Sangin Valley would allow repairs and upgrades to the nearby Kajaki hydroelectric dam. That, in turn, would allow the government to provide more irrigation, water, and electricity to as many as 2 million people in southern Afghanistan.
That would signal to Afghans elsewhere that their living conditions can be improved if they cooperate with the Afghan government. Langton says it also would allow the international community to be seen as an agent of positive change in Afghanistan rather than as an invader and occupier.
Taliban fighters captured Musa Qala in February 2007 after the collapse of a British-backed peace deal with militants in the area. Just before last month's NATO-led offensive to recapture the town, delegates from Kabul met with Mullah Abdul Salaam and won promises for the allegiance of his Alizai tribe. Since then, other tribal leaders in Helmand Province have supported Salaam's appointment as Musa Qala district chief.
Deal-Making, Not Nation-Building
Still, Langton warns there could be limits to the deal. He warns that Salaam's willingness to support the Kabul government doesn't necessarily reflect a strong desire on his part to strengthen Afghanistan as a whole.
"It's a very localized thing because Abdul Salaam fits into the requirements of the Kabul government in that locality. In Afghanistan, typically, deals are struck in the interest of individuals principally," Langton says. "We shouldn't come away from this with a notion that this is a good thing across the board and there is a massive interest in building the nation by Abdul Salaam. He is obviously getting something out of it. And that is how things work."
Afghan presidential spokesman Humayun Hamidzada says Mullah Abdul Salaam's appointment reflects Kabul's policy of seeking to engage in dialogue with moderate Taliban who recognize the country's Islamic constitution and agree not to fight the authority of the central government.
"The president has said before that all those former Taliban who come and accept the constitution and who want to participate in the political process through non-violent means, they are all welcome. And Musa Qala is one example," Hamidzada says.
"Mullah Salam had a role in liberating Musa Qala from the terrorist elements. And he had a role in bringing unity among the different tribes and also among the larger community there. And he is now at the service of his people. And he enjoys the support of the government as well as the support of the people."
Yet the issue of government negotiations with the Taliban has been a subject of heated debates in the Afghan media and in the parliament.
On the one hand, such deals could weaken Taliban hard-liners by creating divisions between local commanders in different parts of the country.
But steps toward a political dialogue with former Taliban officials also could anger politicians from the former Northern Alliance who fought on the side of U.S.-led coalition forces to help drive the Taliban from Kabul in late 2001.
Some members of Afghanistan's upper house of parliament, the Meshrano Jirga, have accepted the principle of negotiating with the Taliban. They argue that improving security in Afghanistan is directly linked to the Taliban's participation in national politics.
The appointment of Mullah Abdul Salaam as the Musa Qala district chief demonstrates that Kabul aims to win over disaffected Taliban commanders who are unhappy about ties between Taliban hard-liners and foreign Al-Qaeda fighters.
Hamidzada stresses that hard-liners still trying to reestablish Taliban rule through militancy have no right to participate in Afghanistan's evolving political dialogue. "As far as other Taliban are concerned, whoever is accepting the [Afghan] constitution and wants to do what they can through the political process, the doors are open to them," Hamidzada says.
But the Taliban's former ambassador to Pakistan, the moderate Mullah Abdul Salaam Zaif, says Kabul will have to talk to Taliban hard-liners too, if it wants real peace in Afghanistan. "The Afghan government wants to reach members of the Taliban individually. And Mr. Karzai himself is trying to contact the Taliban individually," Zaif says.
"But they are fighting for a specific purpose. So until they start trying to resolve the problem in a broader way, I think [the Taliban] will continue to fight."

Negotiations With The Taliban
January 8, 2008 -- In a major step for the program of reconciliation with the Taliban, a former Taliban commander, Mullah Abdul Salaam, has been appointed district chief of Musa Qala, in Helmand Province. Salaam switched sides in December 2007 just before a key battle to secure the town of Musa Qala. President Hamid Karzai has repeatedly tried to lure militant fighters away from the Taliban and into the fold of the government, and his office said Salaam's appointment is "consistent with Afghan government policies."
December 27, 2007 -- Two Western aides were expelled from Afghanistan for allegedly holding talks with the Taliban. British and European officials said the expulsions of a senior British UN official and a senior Irish adviser to the EU mission were the result of a "misunderstanding." Karzai's spokesman said the two men were "involved in some activities that were not their jobs."
December 13, 2007 -- Britain is understood to have given its support to Karzai to negotiate with Taliban militants as part of a long-term strategy to bring peace in Afghanistan. The controversial announcement was expected to meet resistance from U.S. hard-liners, but was seen in Britain as essential, as the country's troops face the prospect of further years of fighting in Afghanistan. The same day, the Taliban's former chief spokesman revealed that top-level talks were under way between the Afghan government and key lieutenants of former Taliban leader Mullah Mohammad Omar.
September 9, 2007 -- Karzai renewed calls for talks with Taliban insurgents, but lamented the difficulty of establishing a dialogue. "We do not have any formal negotiations with the Taliban. They do not have an address. Who do we talk to?" Karzai asked.
April 7, 2007 -- Karzai said for the first time that he had held meetings with members of the Taliban as part of a reconciliation effort. But he ruled out talks with the Taliban leader, Mullah Omar, or foreign militants fighting with the Taliban. The announcement of negotiations with the Taliban was reported to have opened a rift between Karzai's Pashtun backers and mainly ethnic-Tajik northerners, who have coalesced in a new opposition party led by parliament speaker Yunos Qanuni.
November 30, 2006 - Pakistan denied press reports stating that the country's foreign minister was urging NATO countries to negotiate a power-sharing arrangement with the Taliban in Afghanistan and refrain from sending more troops there. Britain's "The Daily Telegraph" reported that Foreign Minister Khurshid Kasuri privately told his NATO counterparts that the Taliban is winning the conflict in Afghanistan, and that the coalition should work toward a new coalition government in Kabul that excludes Karzai.
February 24, 2005 -- Afghan authorities met with four former senior Taliban leaders, thought to be moderate members of the ousted regime, in a bid to get more hardened fighters to surrender. The Taliban's former unofficial envoy to the UN, Abdul Hakim Mujahid, former Deputy Higher Education Minister Arsullah Rahmani, former Deputy Minister of Refugees Rahmatullah Wahidyar, and Habibullah Fawzi, former charge d'affaires at the Afghan Embassy in Saudi Arabia, met with authorities in Kabul.
September 5, 2004 -- Second-tier cabinet officials agreed to a three-phase strategy for dealing with the Taliban: talks, followed by diplomatic pressure and covert funding, and as a last resort, "direct action" to wrest control from the remaining Taliban strongholds.
October 20, 2003 -- Afghan officials report that the government is in talks with prominent "moderates" from the former Taliban regime in an attempt to turn the tide of antigovernment and anti-U.S. sentiment in southern Afghanistan.
