The setbacks effectively paralyze the two main tracks for ending the 10-year-old war. Part of that exit strategy is to gradually transfer authority to Afghan forces while another tack is to pull the Taleban into some sort of political discussions with the Afghan government.

Karzai also said he now wants Afghan forces take the lead for countrywide security in 2013, a year ahead of schedule. He spoke as Afghan lawmakers were expressing outrage that the US flew the soldier suspected in civilian killings to Kuwait on Wednesday night when they were demanding he be tried in the country.

“Afghan security forces have the ability to keep the security in rural areas and in villages on their own,” Karzai said in a statement after meeting visiting US Defense Secretary Leon Panetta. He said he had conveyed his demand to Panetta during their meeting.

Foreign Ministry spokesman Janan Mosazai confirmed that Karzai was asking for NATO to immediately pull back from villages and rural areas to main bases.

Karzai is confident that Afghan security forces know “a thousand times better than any foreign troops the culturally sensitive ways of dealing with their own people,” Mosazai said.

If the NATO troops did pullback, it would leave vast areas of the country unprotected and essentially mean the end of the strategy of trying to win hearts and minds by working with and protecting the local populations.

The American accused of killing 16 civilians on Sunday was stationed on just such a base, where a small group of soldiers worked with villagers to try to set up local defense forces and strengthen government.

Leaving rural areas would also mean pulling back US forces from the border areas with Pakistan.

Karzai told Panetta that the weekend shootings in southern Afghanistan were cruel and that everything must be done to prevent any such incidents in the future. He said that was the reason he was demanding the pullout from rural areas now and early transfer of security.

President Barack Obama and British Prime Minister David Cameron said in Washington on Wednesday that they and their NATO allies were committed to shifting to a support role in Afghanistan in 2013.

Obama gave his fullest endorsement yet for the mission shift, but he said the overall plan to gradually withdraw forces and hand over security in Afghanistan will stand.

In January, after French President Nicolas Sarkozy suggested that foreign forces speed up their timetable for handing combat operations to Afghan forces in 2013, Karzai said he would be in favor of that — if it were achievable.

The call for an immediate exit from rural areas is a new demand however, and it is unclear how it will affect the transition strategy and ongoing talks with the US about how to manage a long-term US military presence in the country.

Karzai is known for making dramatic demands then backing off under US pressure. Even if he eventually changes his tone, the call for a pullback will likely become another issue of contention between the Afghans and their international allies at a time of growing war weariness in the United States and other countries of the international coalition.

The Taleban said it was suspending talks with the US because the Americans failed to follow through on their promises, made new demands and falsely claimed the militant group had entered into multilateral negotiations.

Taleban spokesman Zabiullah Mujahid said in a statement that they had agreed to discuss two issues with the Americans: the establishment of the militant group’s political office in Qatar and a prisoner exchange. The Taleban said the US initially agreed to take practical steps on these issues, but then “turned their backs on their promises” and came up with new conditions for the talks.

“So the Islamic Emirate has decided to suspend all talks with Americans taking place in Qatar from today onwards until the Americans clarify their stance on the issues concerned and until they show willingness in carrying out their promises instead of wasting time.”

“We must categorically state that the real source of obstacle in talks was the shaky, erratic and vague standpoint of the Americans therefore all the responsibility for the halt also falls on their shoulders.”

The Taleban also said Karzai falsely claimed the Afghan government was involved in three-way peace talks with the militants and the US The Taleban said talking to the Afghan government was “pointless.”

Panetta applauded Karzai last month for telling an interviewer that the US, Afghan government and the Taleban recently held three-way talks aimed at moving toward a political settlement of the war.

The Taleban denied the claim at the time.

Afghan officials told The Associated Press that the US had agreed in January to include representatives of the Karzai government in future meetings, but US officials would not confirm that. US officials did say that if this initial trust-building phase of contacts with the Taleban blossoms into full peace negotiations, the US would sit alongside the Taleban and the Afghan government.

The secretary of the Afghan peace council, which has been pushing for talks between the Afghan government and the Taleban, said it was not clear why the Taleban stopped negotiations with the United States.

Mohammad Ismail Qasimyar speculated that it could be related to the Taleban’s request that five top Taleban leaders be released from the US military prison at Guantanamo Bay, Cuba.

He said Afghan government needs to be involved in the negotiations.

“In the past, we did a lot of preliminary work to build trust and goodwill for talks,” he said, if the Afghans are not involved, any peace process won’t work.
