Let me put some points forward considering recent events.
1. Growing anger against Pakistan Army - US drone attacks, ANA shelling across the borders and recent report on missing people and human rights violation have attracted many people and especially media, which is regularly bashing Pakistan Army. OBL was also one of the biggest blow to capability of Pakistan Army in eyes of people of Pakistan. Pakistan Army needs people's support.
2. TTP factor - TTP got created when Pakistan supported WoT. Now they have shown their capabilities in strike at heart of Pakistan, regular bombing, kidnapping and beheading soldiers and attacks on military bases. The recent declaration by TTP saying that they will fight against India gives Pakistan Army a chance to have back channel talks with TTP.
3. Post 2014 Scenario - We all know many factions in Afghanistan who are fighting NATO forces will get back at Pakistan after NATO withdrawal as Pakistan was ally of NATO in WoT. This will lead to mushroom growth of anti-Pakistan elements which may turn out more dangerous than TTP and BLA. This is the last thing Pakistan wants know as it will lead to decade long insurgencies.
Pakistan has to show same approach to Afghan Taliban and anti-India factions as India is increasing it influence in Afghanistan and is pro-Karzai, to kick out India from their western borders.
Pakistan needs to channel these Taliban forces against India rather than they attacking Pakistan.
There are other factors too. Pakistan Army needs public support more than ever.
OBL happened nearly 2 years ago, the Drone Strikes have been happening for quite some time, the ANA shellings have been befittingly replied back in the past & will be this time as well.
Thankfully the media has now toned down on the 'Missing Persons' thing & that issue has almost died out with more & more media personalities taking criticism from their own quarters, the civil society & the general public by actually going to those areas to find out what is happening. As far as I know the last person who did that (Wajahat Khan from Quetta himself) visited those areas, posed provocative questions to the military there, talked to captured militants, toured the relief & development work done by the Army & the F.C & made a documentary about it ! Either way the insurgency in Balochistan is loosing its footing because finally the 'other side' has decided to start speaking up; the Kalpar Bugti's have never been as vocal as they were now & the so-called Freedom Fighters sitting in Switzerland haven't been as quiet as they are now.
TTP is a dying breed that would be eventually hammered out through the 'development work' & the 'consolidation' done by the Army & the F.C ! Either way the attacks have reduced down substantially to a point where suicide bombings are down to once every few months instead of once every other week. Additionally the vindictiveness & the shamelessness of the TTP in attacking the little girl from Swat has shook Tribal Society to its roots, the capture of Uzbek, Chechen & Arab Mujahideen from our Tribal Areas working as part of the TTP has angered the Pashtun element greatly, the association of the TTP with the Mehsud Tribe has further emboldened the Wazirs & other Pashtuns to strike their own claim.
You can ask @
Hyperion more about the above !
One would be wise to note that alongside the Tribal Lashkars, the F.C is composed of, not only Pashtuns but at that Tribal Pashtuns & are the two elements that are fighting the TTP most vociferously !
The TTP's recent 'peace offering' has gone unnoticed partly because we feel that we have the upper hand, partly because we've tasted that in the past & partly because their sincerity was measured up with their response of kidnapping Pakistanis the very next day.
As for the Post-2014 Afghanistan :
On one hand the Haqannis are, in Panetta's own words, 'the veritable arm of the ISI' & on another they are going to turn back & fight us ?
That doesn't add up for me !
Secondly you have to understand that most of the Taliban are not :
(a) ideologically motivated this time around
(b) the Taliban Movement is as much, now, about Pashtun Nationalism, Afghan Independence as it is about Political Islam.
So when the ANA is, virtually, the Northern Alliance with a make-over, the Pashtuns aren't just going to sit back & be abused at by them Farsiwans !
The Afghan Taliban don't attack us not because they can't for they are practically in Pakistan but because they don't need to or want to. They have, however, repeatedly castigated the TTP to behave themselves & concentrate solely on fighting the Americans.
Once the Americans leave Afghanistan the Taliban are going to have their eyes set on Kabul & defeating the ANA something that Pakistan would, covertly, but surely support ! Whatever bad feelings we had have been mended over the years, there is after all some truth in the Americans not trusting us.
Besides Pakistan does not need the Taliban to hold their own against India & a whipping of insurgency in Kashmir isn't very big on our cards (the Kashmiris themselves are doing that peacefully as we speak !). We'd much rather sit back & lick our wounds to recuperate from 12 years of war.
And the Pakistani Army garner public support by taking out two Indians is amusing at best ! Had the army wanted to do that they're more than qualified to put up a much...much better spectacle than just 'cross-firing resulting in two deaths' !
