Taimi khan you are such a senior member, yet you ask such a stupid question. I am sure you are acting ignorant here. SO here, take this from a newbie.
The Value of OBL to pakistan was that pakistan could perpetually milk dollars out of USA by constantly showing them the threat of Al-keeda and OBL for years and years to come. You have taken billions of dollars from US since 2001 for finding OBL and you would have perpetually looted US tax payers money by taking Aid on one hand and hiding OBL on the other hand.
It makes business sense for pakistanis, who have no other means to earn money, or buy state of the art weapons, or to pay their international loans. To find a perpetual customer who pays for your efforts to fing and eliminate OBL and Al-keeda. OBL was an ACE for pakistan and as a insuarance policy to make Americans pay to PA for efforts it takes to find OBL and eliminate Al-keeda.
OBL was not found in FATA or khyber, He was right inside millitary cantonment area. Near your reputed millitary establishment. Living in house that has 18 feet walls and barbed wires.
