> Ahmed Wali Karzai, the brother of the Afghan president and a suspected player in the country’s booming illegal opium trade, gets regular payments from the Central Intelligence Agency, and has for much of the past eight years, according to current and former American officials.

...

> Now, with more American lives on the line, the relationship with Mr. Karzai is setting off anger and frustration among American military officers and other officials in the Obama administration. They say that Mr. Karzai’s suspected role in the drug trade, as well as what they describe as the mafialike way that he lords over southern Afghanistan, makes him a malevolent force.

> These military and political officials say the evidence, though largely circumstantial, suggests strongly that Mr. Karzai has enriched himself by helping the illegal trade in poppy and opium to flourish. The assessment of these military and senior officials in the Obama administration dovetails with that of senior officials in the Bush administration.

This is the truth.The war on drugs is a war on people. Did you know that in 2000, opium production had almost completely stopped in Afghanistan, thanks to the Taliban? That’s like 80% of the worlds supply of heroin. The global market value of heroine is like half a trillion. Where do people think intelligence agencies get all of their black money from? That’s the real reason that we went to Afghanistan.

I've read that before the Taliban banned production they stockpiled a lot of it, then when prices skyrocketed they sold their reserves at a much larger profit.

That’s very interesting, especially the timing.
