The Taliban are open to a general ceasefire as well as a political agreement which could lead to a US military presence in Afghanistan up until 2024, AFP reports citing a new report by a British think-tank.
But the insurgent group, led by Mullah Omar, will not negotiate with President Hamid Karzai or his administration, which it sees as corrupt and weak, the briefing paper by the Royal United Services Institute (RUSI) says.
The report, entitled "Taliban Perspectives on Reconciliation", presents interviews with four senior Taliban representatives about their approach to reconciliation.
The paper claims to reveal an emerging, pragmatic consensus among the Taliban leadership, who are willing to take part in peace negotiations in exchange for political leverage after 2014.
NATO has about 130,000 soldiers fighting a decade-long insurgency by the Taliban, but they are due to pull out in 2014 and now work increasingly with the Afghans they are training to take over.
The report says the Quetta Shura Taliban, a council of Taliban leaders headed by Omar, will not accept the interpretation of the Afghan constitution in its current form since this would be akin to surrender.
But Taliban representatives did welcome the prospect of a US military stabilisation force operating in Afghanistan up to 2024 out of the five primary military bases -- Kandahar, Herat, Jalalabad, Mazar-e-Sharif and Kabul.
However, this was only as long as the US presence contributed to Afghan security and did not constrain Afghan independence and Islamic jurisprudence, the report said.
The paper also warned any American attacks against neighbours -- such as Iran and Pakistan -- launched from Afghan bases would not be tolerated since it would impact on national security and invite "trouble".
The report's authors met in July with one former Taliban minister, one ex-Taliban deputy minister and founding member of the Taliban, one senior ex-mujahideen commander and lead negotiator and one Afghan mediator who had negotiated with the Taliban.
The paper was written by Anatol Lieven, Theo Farrell and Rudra Chaudhuri from the Department of War Studies at King's College London, together with Michael Semple from Harvard University's Carr Center on Human Rights.
The report highlights that the primary view of all four representatives was that if any agreement with the Taliban were to be successful it would require endorsement by Omar, who is open to negotiating a ceasefire as part of a general settlement.
So far no Taliban leader has publicly endorsed the idea of a ceasefire, the report said.
The paper also found that the Taliban leadership and 'base' deeply regretted their past association with Al-Qaeda, so much that once a ceasefire or political agreement were decided they would obey a command to completely renounce Al-Qaeda, as long as this call came from Omar.
One interviewee noted that any renunciation process would be used "as a lever to negotiate something substantial."
