I wouldn't call that stability. After both the Soviets and the CIA pulled out, the warlords first conducted a terrible civil war. That civil war was kind of ended by the Taleban, which conquered most of their territories. Then the US let the warlords back - but they conduct their own fiefdoms, their soldiers are no better for the population than the Taleban (in fact, some Afghanis say, worse: by allowing free reign of common criminals), clash with each other ocassionally - and all the while the Taleban conducts a guerilla campaign, lately with Iraq as the model.
