How and Why would PA go after OBL prior to 9/11? You wanted PA to find and kill OBL in Afghanistan in the 90s? This makes no sense at all, especially considering the username you have chosen for yourself.
And yes that assumption is correct as these problems were not as prevalent before the 90s, and only got to this worse state after joining the afghan war in the 80s and then again in 2001.
PS. F16s were all paid by Pakistan. CSF is for supporting PAs operations in FATA, providing security to convoys etc. Again these benefits are peanuts compared to the 100 bln + loss to our economy and 40k + civilian lives lost.
OBL was openly calling for war with USA before 9/11. He ordered the hits on East African embassies. Do not tell me the PA could not put a crimp on his operations. Most of his operatives are flying through pakistani airports into afghanistan
