A recent Rasmussen Reports telephone survey of likely voters finds that just 41 percent “now believe it is possible for the United States to win the nearly nine-year-old war in Afghanistan.” More to the point, a plurality of 48 percent now say ending the war in Afghanistan is a more important goal than winning it.
The war in Afghanistan has not been about any kind of "war on terror" because Afghanistan is not a threat to the US.
This has been a war on people, cursed with the really bad luck of living over a country whose resources - and access to resources - the US government has decided belongs to them.
This has always been about potential profit from oil, drugs, and mineral rights, and never about Afghanistan being a threat to the US.
The US government and NATO should declare victory, bring their troops home, and negotiate with whatever government is left standing in Kabul for the oil pipeline and mineral rights.
Of course, that would be logical.
