There's considerable evidence and reason to believe Washington invaded Afghanistan in 2001 to supercharge opium production (banned by Taliban) and flood/destabilize the region (China, Iran) as part of a deliberate, covert and asymmetric drug proliferation strategy.
Now, you could argue that the subsequent invasion of Iraq was counterproductive to that, but I don't see that argument having water.
