Afghanistan kind of remind me of the Vietnam War. Not only there is a lack of purpose but a lack of strategy. I suppose our initial goal was to create a pro-US Afghan government and military that can stand against the Taliban in the same way we tried to create a pro-US South Vietnamese government and military that can stand against the NVA. We failed in South Vietnam because we lacked the will to finished the job and left South Vietnam on a major lurch that led to their downfall in 1975. And right now, the lackluster attitude toward Afghanistan may result in the same result.
