re: In Afghanistan there are the three you mentioned.
"There are the insurgents, the Taliban and al-Qaeda.
There's a third side, the narcotics industry. They are wealthy and determined, and even now have corrupted the tribal leadership and Karzai's government."
Now, "Which is the fourth side. The US and NATO trying to overcome the Taliban and al-Qaeda, the narcotics trade and large elements of Karzai's government."
What's wrong with the fourth side you mentioned above? If it wasn't for them we'd have more drugs and terrorism spread world wide not to mention Afghanistan itself.
Good grief, Bowser!
