Any fool can understand that continuing our 17-year-old war in Afghanistan is a fool’s errand. The nation is artificial. Among other things, its disputed border with Pakistan, the Durand Line, was drawn in 1896 between the British Raj and Afghan Amir Abdur Rahmen Khair. Afghanistan’s population splinters along tribal, ethnic, and sectarian lines, including Pushtans, Uzbeks, Hazara, Tajiks, Turkmen, and Balochi. Its government is riddled with nepotism, corruption, ineptitude, and lawlessness. Election fraud and political sclerosis are endemic. Opium production and trafficking replenish the Taliban’s coffers.
