Imran Khan never understood the threat of Al-Qaeda Network, an organization that was courting and funding TTA in the 1990s and Pakistani tribal groups that collectively formed TTP in 2007. Al-Qaeda Network was brainwashing and recruiting people for its terroristic causes.
US came to dismantle Al-Qaeda Network in the region and put pressure on Pakistan to dismantle Taliban groups in tandem. But Pakistan allowed TTA to rebuild itself and negotiate with TTP. Ex-COAS Raheel Sharif gave a good thrashing to TTP but it was able to regroup in TTA-controlled sectors in Afghanistan while Pakistani were busy bashing US-backed Afghan setup. Imran Khan allowed TTP to return to Pakistan. This policy of appeasement is why the War On Terror continues for Pakistan.
1. TTA supports TTP.
2. TTP demands removal of Pakistan Army from tribal regions.
3. Afghans do not accept Durand Line as border.
4. BLA is also able to find space to do its bidding.
How Pakistan can move forward from this mess and realize those wonderful goals you have in mind?
TTA will approve regional interconnectivity projects to the benefit of Afghanistan and not out of love for Pakistan. TTA wants to reduce dependence on Pakistan to meet Afghan economic needs.
Pakistan's (Alice in the Wonderland) Afghan policy has damaged US - Pakistan relations and India will benefit from this situation. Heck, TTA has invited India to complete its projects in Afghanistan.
Strategic depth, my friend.
Why you blaming US in this matter? As if you do not know what was going on? See my post above.
You need to understand that Pakistan has to rebuild relations with the US. There are no alternatives to this market and power.
US has given Pakistan breathing space with recent IMF bailout package. It is due to this package that GOP is able to increase salary package of many people to help them cope with rising inflation.
