calling him "a high-level official" is somewhat misleading. Hoh's four page letter is worth reading, and my own guess would be that he is in many ways correct
Some years ago, American cold-warriors were excited by the idea that the USSR might be lured into a war in Afghanistan that could damage the Soviets much as Vietnam damaged the US. They therefore deliberately engineered some incidents in Afghanistan, which they hoped would be read with alarm by the Kremlin. And a Soviet intervention, in support of the then-existing Afghan government indeed followed. The cold-warriors then insisted that the US should support religious extremists in Afghanistan: “These gentlemen are the moral equivalents of America’s founding fathers,” Reagan said in 1985. America provided weapons and other support. When the Soviets withdrew, the US had essentially no further interest in the ruined country. The extremists, however, were now armed and organized -- and they took over. The cold warriors regarded the extremists as friend, and maintained some usable contacts with them. The extremism of the Taliban, and its tolerance of al-Qaeda training camps, was well-known, when (long before 9/11) the GWB administration, motivated by petroleum interests, hosted Taliban at the White House and provided them millions in "drug war" funding. The Bushistas, of course, wanted to use 9/11 as a pretext for a general war in the area, aimed not only at Afghanistan but at Iran, Iraq, and Syria -- with rather little interest in Afghanistan:
Secretary of Defense Donald Rumsfeld .. suggested bombing targets in Iraq .. and when he was told .. the enemy is in Afghanistan, that's where the Taliban and al Qaeda are, Rumsfeld .. said but there are no good targets in Afghanistan, there are lots of good targets in Iraq http://transcripts.cnn.com/TRANSCRIPTS/0403/22/ltm.03.htmlRumsfield has not been not alone, in regarding Afghanistan only as a warfield, without much regard for other issues affecting people's lives there. After 9/11, we should have attempted a reconstruction of Afghanistan, still in ruins from the 1980s, but we did not: instead, we made a short military stab at the Taliban and al-Qaeda, before blundering off to Iraq, Afghanistan being largely forgotten, except by the Afghanis and the troops sent there
