You do know that Kevin's tweet has personally named Imran Khan for the reason why he could not confirmed to tour Lahore.
I can understand his decision not to tour Lahore due to security grounds, but in his tweet did name Imran Khan. Now Kevin might be back-tracking due to potentially politically backlash that might affect his brand in PSL or something along with that lines in regards to his brand in PSL.
I was actually surprised Imran Khan was named for the reason given his popularity that touches Peshawar and all over Pakistan, not only that they were chanting 'Go Nawaz Go' not long ago.
Pietersen is being smart to back-track his statement in order to preserve his brand in PSL.
And may I remind you chotay Sharif sahab is on record of having asked the Taliban to spare his beloved Punjab when attacking locations in Pakistan. Wow so much inter-provincial harmony.
On bold;
That is because Zardari was federal government of Pakistan who had no intention of launching military operation despite the insistence from General Kiyani. And the public was on Imran Khan's side in regards to Imran Khan's peace proposal with TTP.
That chotay Sharif was chief of Lahore meaning his administrative levels is strictly limited, hence begging TTP to leave Punjab since both Zardari aka Federal Government and Imran Khan were not in mood for military operation.
Under Nawaz Sharif's leadership, it was not coincident why Pakistan launched Zarb-e-Azb with the cooperation with General Raheel brought by General Kiyani in COAS meeting. Imran Khan was in foul mood back then, and still is.
It is important to provide the background to support the whole context, otherwise with little info to none can be easily misinterpretation. That chief minister of Lahore was begging, not making deal because Chief Minister of Lahore had no administration levels to make deal and still don't.
