As we wrap up the war in Afghanistan, it's worth noting, many a major empire throughout history has invaded Afghanistan going back to Alexander The Great, including in modern times, the British and Soviets.
And the big question I keep thinking is why?
There's nothing there of value, except maybe some poppies, but there's easier ways to synthesize and less remote places to grow those. Osama wasnt there, nor any credible threat, as it's mostly primitive.
Some sort of ancient secret? Antedeluvian knowledge?
