"They" did not. I repeat, no one had an Afghan passport. No one got Afghan funds. The country has been locked down for a year, and under intense scrutiny even before that.
I think you need to find out who exactly "they" are before you go off half-cocked and kill everyone whose looks you don't like.
McVeigh killed 168 people. We didn't bomb his home town or kill his parents, did we. Oh, but he wasn't one of "them" so it's cool.
No, we did not shoot McVeigh's family or friends. We did not burn down his home town. But they cooperated with authorities. If they had not, they would have been arrested, and rightfully so. If they had resisted, they would have been killed or captured, and righfully so.
A crime was committed. An extraordinary crime requiring extraordinary response. The perpetrators are guilty. The planners are equally guilty. But so are those that hosted the perpetrators and planners if they knew that their guests were planning such an activity and especially afterwards, if they refuse to turn over the criminals. Refusing to do so makes them accessories to the crime -- accessories after the fact. In the eyes of the law, accessories are just as guilty as those who flew the planes into the buildings.
If the Taliban do the right thing, turn over bin Laden and his merry men -- there is no need to declare war on Afghanistan. If the Taliban are incapable of arresting bin Laden and his organization, then they need to get out of the way and let us do it. If they are unwilling to do that, well, then they are accessories after the fact, and my sympathies stop right there.
Yeah, innocent Afghans will suffer. But that is the choice of their government. And I have news for you -- 99 and 44/100th of the Japanese citizens in WWII had nothing to do with bombing Pearl Harbor. They were innocent citizens. But they were put in harms way by their government, and suffered accordingly. So, too, with the Afghans, the Pakistanis, the Iraqis -- or anyone else whose government participated in this attack, and refuses to cooperate with the United States.
