I guess we didn't realize the plan all along.

1. Start with America's incomprehensibly large thirst for energy
2. Start a war to destabilize oil energy from the Middle East
3. Watch costs go up all over, especially food
4. Watch Afghanistan liberate itself from the poppy crops

It's all so amazingly obvious that I'm ashamed I didn't see it before this:

The sky-rocketing cost of wheat is breaking food budgets around the world. Families are paying more for bagels in Brooklyn and for flatbread in Afghanistan. The difference is that many Afghans are now spending half their earnings on bread alone. International aid is keeping the country — one of the world's poorest — from food riots and starvation. But the crisis may encourage some farmers to move out of the drug trade and into wheat.

Well, I suppose if they had told us the plan it wouldn't have worked...
