Oil man Cheney wanted to open Afghanistan to a pipeline project.
Gore probably would have used special ops teams to locate and extract bin Ladn.
Also, the Taliban destroyed statues of the Buddha that had stood for centuries. That happened in March of 2001. The Bush administration didn't want to hurt the oil deal, so they let the Taliban go ahead. Gore might have done more to stop the destruction. Seeing America take a firm stand on a minor issue might have deterred the Afghans from allowing bin Ladn to hide there.
Another thing. There was a report issued before the 9/11 attack. If Gore had been President, the White House might have acted to stop the attack.
