Because there was Congress hand behind it.
But when MMS govt. allowed free hand to Sri Lanka, it took no more then 3 yrs to clean the whole shit.
so india supported an ethnic insurgency in SL for 27 years? And india supported SL in fightin it?
I. The 80s it was PaK that helped SL Military raised its special forces,the even selected locations for their SF HQs,fAcilities.. provided them weapons and Sen military advisors.. Even during the las years india was reluctant in supporting SL .. It was Pak that was sending armed supplied,
/ships ,military advisors every week to help SL military. It was Pak that was standing with SL when india was opposing SL at UN.
Again fightin an ethnic insurgency militia in a region locked by sea is nothing when compared to taliban... Even NATO has failed (with taliban controlling t most of Afghanistan today)... even after 14 years!
Remember an insurgency like Khalistaan movement took 20 yrs to clear out from whole India.
Again fighting an insurgency in the plains of punjab .. Locked between Pak (LOC) on one side indian heartland on the other.. It still took you 20 years to deal with lightly armed Sikhs.
Now take into account the terrain of FATA (the same region high even british couldn't control)... The porous border with a war torn country,abundant arm supposed,venomous ideology that encourages attrocities like suicide bombings etx... The foriegn funding,hardcore militants from almost every corner of this part of the world .. from Chechnya to Libya..
The limited resources of Pak with its crippled economy.. Yet today after the launch of NWA we have almost cleared the entire region with the leadership of taliban either dead,dying for fleein to Afghabistan..
