Indeed, the drug trade is a crucial part of Afghanistan’s economy, both in regions that the Afghan government controls and in Taliban-dominated regions. The Kabul government estimates that at least three million farmers make their living from that crop. In a desperately poor country, such income is often the difference between a decent lifestyle and destitution. U.S. leaders face a hopeless dilemma. If they press the government of President Ashraf Ghani to increase eradication efforts, then that move will alienate beleaguered farmers and drive them into the arms of the Taliban.
