It's facile to assume a moral equivalence between one side accidentally killing civilians in situations where it's extremely difficult to isolate the enemy, and the other side hijacking jetliners and flying them into office buildings.
Agreed. But please do note that the Taliban didn't fly any aircraft into buildings. The ones who did were Saudis. The Taliban want to kick the invader out, just like the Vietcong 40 years ago. If you think the war in Afghanistan is motivated by the desire to kill Al Qaeda, you need to read a thing or two on geopolitics.
Al-Qaeda are about as Saudi as the IRA is British. The people who make that argument, and forget the close ties between Al-Qaeda and the Taliban in the first place, are the ones who need to read a thing or two on geopolitics.
