SEATTLE — When the Soviets concluded their pullout from Afghanistan in February 1989, the U.S. government abruptly lost interest in the country. A devastated economic infrastructure, entrenched poverty, deep-rooted factionalism and lack of international aid caused the country to descend into complete chaos. Internal violence also worsened. All that mattered to America was that the Cold War rival had been defeated.

Afghanistan remains the starkest illustration of how poor countries are used, then betrayed when their usefulness runs out. But Afghanistan is not an exception; U.S. relations with many other countries, including Pakistan, Somalia and the Palestinian Authority remain hostage to this very model.

Yemen is now emerging as the newest casualty. Its government is desperate to hold on to the reins of power amid corruption, extreme poverty and untold Western pressures.
