Well to remember that the Civil War was the "war between the states, and not the war within the states; and not attempt too much to draw parallels that apply to an internal insurgency such as is taking place in Afghanistan.
That is only partially true and misleading in a respect. If we could simply erase Pakistan from the equation, then it would be an internal conflict, but the reality is that is a hybrid conflict that doesn't conform to simple definitions. It is part insurgency, part anarchy, part surrogate/UW, part global non-state actor inspired/supported, etc. This isn't Malaya or the Philippines (which we all understand, yet we still want to focus on a narrow COIN strategy).

The principles of civil emergency apply, and best to remember that such emergencies are almost always well rooted in some fundamental failures of government, rather than failures of populace.
This is definitely a large part of the problem, but not "the" problem. This statement assumes that if Afghanistan had a functional government that Pakistan and non-state actors would cease hostilities. While neither of us know, I suspect that isn't true, and I also suspect that "we" can't fix the Afghan government, so using that as a strategy is flawed from the outset.
