The Reason the US went to Afghanistan was because of 9-11, where some 3400 civillians were killed in the US. The same outrage felt by Afghanistans about the 16 people killed by a rogue US soldier, was felt by the West, for 9-11, for the 3400 civillian deaths.
How much has the US spent to keep civillians safe from terrorist acts? No Fly lists, screening luggage, searching airline passengers, improving aircraft and airport security?
The Taliban had no idea that Al Qaida was planning civillian deaths in the West? You are claiming that the Taliban and no Afghans assisted Al Qaida in any way with 9-11? Afghanistan was a haven for anti-Western terrorist groups, leading up to 9-11.
Afghanistan has been a source of Opium and Marijuana, and has resulted in drug overdose deaths in the US. The drug trade invites violence in the distribution process of drugs. Afghanistan is a central core of violence in the West.
"2000 - causes of death - illicit drug use) "Illicit drug use is associated with suicide, homicide, motor-vehicle injury, HIV infection, pneumonia, violence, mental illness, and hepatitis. An estimated 3 million individuals in the United States have serious drug problems. Several studies have reported an undercount of the number of deaths attributed to drugs by vital statistics; however, improved medical treatments have reduced mortality from many diseases associated with illicit drug use. In keeping with the report by McGinnis and Foege, we included deaths caused indirectly by illicit drug use in this category. We used attributable fractions to compute the number of deaths due to illicit drug use. Overall, we estimate that illicit drug use resulted in approximately 17000 deaths in 2000, a reduction of 3000 deaths from the 1990 report."
