Are you being sarcastic?
I was no more sarcastic than you were.

Opium production has sky-rocketed under the Taliban.
Bullshit.

Opium production sky-rocketed after establishing the new "democratic" regime, and everybody knows that. Also, everybody knows that Kosovo is not an independent state, it's just a logistic centre for opium distribution.
Market forces - supply and demand - will establish production rates. Momentary blips are efforts at some entity attempting to influence market forces.
Start with that idea.
Then explain how motives for war could possibly encompass "increasing or decreasing opium production."
It's a good slap at the USA, but it's totally illogical.
