And also it should be remembered, borders were vague ideas,
And in the case of Afghanistan, these still are vague ideas, as is the very idea of a such a "geo-political unit" as Afghanistan.
Its central government never has excercised much control over the regions, certainly no more than each local ruler allowed it to have:
- a situation making the place all but ungovernable.
Also, when you have such major population groups as the Pashtuns resident on both sides of an imaginary line designated "border" - a line that is crossed by few roads, but many thousands of unpoliced mule tracks - the term "border" comes to mean very little!
