I know, I know: optimism is so crazy!
The Taliban, in a fit of self-preservation, detains and hands over Osama bin Laden to a U.N. tribunal. No U.S. soldiers set foot in their country, no further lives are lost over all this. Worldwide, formerly terrorist organizations renounce methods which might lead to the death of innocent people (much like the Protestant protesters in Northern Ireland recently stepped back once one person "crossed the line" with bomb-throwing).
