If guerilla warfare were that good then why isn't the then why has the taliban tried to fight like a pseudo conventional force and why is the NA striving for such a force?

quite simply you don't get great strategic victories with a geurila force. That type of warfare is mostly good at demoralizing and waring down your opponent and making them want to give up.

Much larger more decicive gains can be made with a standing conventional force. Just look at the history of how it was used in the past. . . it has always been used by the underdog when they have no other choice. It also has not been a strategy that has always paid off nor has it been rather kind to its proponents in casualties (remember the NV body count from vietnam compared to ours?).

I like our current strategy which is quite simply: strike from where they can't attack you(don't offer them targets to fight back on), and strike the targets that make a difference, and let the indigenous uprisings do the rest.
