There isn't really much to add to this from the Daily Times;
A tense calm prevailed in North Waziristan’s headquarters of Miranshah on Wednesday after "the arrival of eight tanks and [army] reinforcements", sparking fear among locals that the army was preparing to launch an offensive against the Taliban.
This follows skirmishes between security fores and militants along with battling pamphlets full of propaganda, with either the army or the militants claiming the other to be pawns of foreign agents.
It wasn't all that long ago that the Taliban leadership in the area warned of outright warfare should the Pakistani security forces try to seize control of North Waziristan. Said Taliban leadership struck a deal with the Pakistanis before the anti-Mehsud operation Rah-E-Najat in much of South Waziristan- this peace deal granted the Pakistani security forces permission to pass through the territory of Mullah Nazir in South Waziristan and the agency of North Waziristan. Since the signing of that peace deal, it's become no secret at all that Pakistan has been aiding and abetting the drone campaign in North Waziristan that is more despised than anything else by the militants in the region. Pakistan also detained top members of the Afghan Taliban, once seen as "good Taliban" by the Pakistani army and intelligence apparatus.
As spring arrives so will the anti-Taliban offensives in northern-FATA(perhaps Mohmand now that Bajaur appears clear) and central-FATA(parts of Khyber but especially Orakzai). Where it goes from there is far from certain, but what is clear is that the Taliban of North Waziristan are starting to expect a big fight. So must be the Taliban on the other side of the border who know that NATO wants to stay on the offense.
At this point, I would like to re-recommend this piece that appeared in the New York Times called "The War In Pashtunistan". Read about the hammer and the anvil, because that is what the U.S. aim is for the AfPak region.
