Instead of fighting a war we can't win, we could buy the drugs. Burn it if we want. Sell it if we're smart. It would be cheaper and better than sending soldiers into harm's way. Perhaps just $300,000,000 a year. That's what they say the Taliban makes in drug profits (though I suspect it's higher). But instead, we'll fail to end the drug trade and push more farmers into poverty and the hands of the Taliban.
