The 3rd Afghan War will probably follow the same route as the 1st and 2nd.
I suggest we invite the Russians to invade (again) only this time we won't let the CIA provide the terrorists/insurgents/freedom fighters with Stingers.
My two step solution to the drug problem is:
Year 1: negotiate with the poppy growers, offering cash crop alternatives; amnesty for the drug dealers; sensitive medical treatment and support for the users.
Year 2: Napalm the poppy fields, shoot the dealers and cold turkey for the junkies
Problem solved.
