Thomas Schweich in the New York Times Magazine:
On March 1, 2006, I met Hamid Karzai for the first time. It was a clear, crisp day in Kabul. The Afghan president joined President and Mrs. Bush, Secretary of State Condoleezza Rice and Ambassador Ronald Neumann to dedicate the new United States Embassy. He thanked the American people for all they had done for Afghanistan. I was a senior counternarcotics official recently arrived in a country that supplied 90 percent of the world’s heroin. I took to heart Karzai’s strong statements against the Afghan drug trade. That was my first mistake.
Over the next two years I would discover how deeply the Afghan government was involved in protecting the opium trade — by shielding it from American-designed policies. While it is true that Karzai’s Taliban enemies finance themselves from the drug trade, so do many of his supporters. At the same time, some of our NATO allies have resisted the anti-opium offensive, as has our own Defense Department, which tends to see counternarcotics as other people’s business to be settled once the war-fighting is over. The trouble is that the fighting is unlikely to end as long as the Taliban can finance themselves through drugs — and as long as the Kabul government is dependent on opium to sustain its own hold on power.
