Afghanistan and the War against Drugs

Not sure what I actually think of the article or the comments following after it. But the whole problem is really interesting: how exactly can a foreign government help another nation, each with its own internal politics, reduce its drug protection? Or is it a lost battle and should be given up on as such? Moreover, should we even attempt to curb the farming and production of illicit drugs? Would it be better to just make them legal and astound ourselves by the consequent reduction in demand?
