Please make use of your pathetic brain before you ink something.
The possibility of a joint team was set off the day OBL was killed. It was under discussion since then and the modalities were being worked out. This further strengthened when the US handed over the list of most wanted terrorists to Pakistan - at this point the joint venture was almost finalized. This didnt make news as it might 'hurt' feelings. i know this because i should know it.
Here:
US hands over 'most wanted terrorists' list to Pakistan
28 May:The United States has handed over a 'most wanted terrorists' list to Pakistan, expecting it to provide intelligence about them immediately and possibly target them in joint operations, according to a US official and a Pakistani official.
Further, on 2 June the news regarding formation of the team was almost out:
US-Pakistan form an anti-terror squad: report | World | DAWN.COM
US-Pakistan form an anti-terror squad: report
And then on 3 June:
Pakistan confirms joint intel operations with US | Pakistan | DAWN.COM
Pakistan confirms joint intel operations with US
Also, Kashmiri was at nuymber 4 in this list that was handed over to Pakistan.
But most importantly, a simple fact that you chose to omit (either deliberately or because of your shallow knowledge) was that the ISI and the CIA has been working together since the dawn of this WoT, they have been sharing intel, info and targets (must have heard the drones taking off from Pakistan and Pakistan providing the yanks with the ground intel etc, right?), but this was not exactly made public (though it was an open secret)as your likes might start extracting
maja out of it.
So, this joint team was not an 'out of the box' idea, or something that would take weeks or months to plan. At best, since R.Davis issue, there might have been a stop on the intel sharing between the two agencies and the OBL became the nail in the coffin, but then when it was decided to re-work together, it's just like plugging in the RJ-45 connector behind your laptop so that every one becomes online (this i say both figuratively and what actually that might have happened).
So, like they say:
Gadhay k sir pe seengh nahi hotay
