But the BBC's Syed Shoaib Hasan in Islamabad says circumstances suggest the militants are now under pressure and that a national consensus is building among the public and political parties that they must be challenged with force.
Pakistan's government has clearly stated that unless the Taleban lay down their arms, other options will be considered.
Pakistan's chief of army staff Gen Ashfaq Kayani rejected criticism of army inaction in Malakand.
"The operational pause, meant to give the reconciliatory forces a chance, must not be taken for a concession to the militants," he said.
Sympathy for the militant movement has been on the decline, our correspondent says, since the airing of footage showing a young girl being flogged as a punishment in Swat.
Although the Taleban denied ordering the punishment, their public standing has plummeted.
US Defence Secretary Robert Gates warns of the Taleban threat to Pakistan
At least 10 more paramilitary platoons totalling about 200 men have now arrived in Buner to take control of government buildings.
The latest moves followed a meeting of government officials in North West Frontier Province to discuss the faltering peace deal.
Ahead of the meeting provincial spokesman Iftikhar Hussain had said: "Those who took arms must lay them down. Those who went to Buner, they must get out from Buner.
"This is the only way, and we are asking them for the last time."
The Taleban had been expected to lay down their arms under the peace deal and allow police and other officials to resume their duties.
However, the Taleban had further consolidated their hold on Buner.
On Wednesday they ambushed a paramilitary convoy at the border village of Totalai and prevented it from reaching Buner's central town of Dagar.
The US had expressed deep concern over the developments.
On Wednesday, Secretary of State Hillary Clinton said Pakistan posed a "mortal threat" to the world by abdicating to the Taleban.
On Thursday US Defence Secretary Robert Gates warned Pakistan that relations with the US would be threatened unless Islamabad combated the rise of the Taleban.
