The Taliban's resurgence in Afghanistan has so far been concentrated in the south and east of the country, but according to a new report, they could emerge as a national insurgency within two years. Gilles Dorronsoro, an analyst at the Carnegie Endowment for International Peace, writes that the Taliban's rapid expansion is the result of its own operational strengths, both in terms of strong leadership and effective propaganda, combined with the West's continued underestimation of its powers. With increasing numbers of US troops bound for Afghanistan, Dorronsoro recommends that they be posted to areas in which the Taliban have yet to concentrate in order to prevent these regions from falling victim to insurgents. "If the Coalition reinforced the Afghan police and military in the North," he says, "the insurgents could be stopped relatively easily."
