Make it possible for US forces to capture or kill Osama Bin Laden successfully in December 2001 before he can escape into Pakistan via the area around Tora Bora.
Yes, but the easiest way to have it happen is the U.S. changes the whole war plan and focuses on controlling the exists to Iran and Pakistan before the bombs start dropping.
Bin Laden after he excaped into Pakistan stayed only symbolically important anyway. Power inside the jihadi movement devolved to his old friend and sometimes competetor Zarqawi who was leading the fight in Iraq while he hide out and handed over operational control of al-Qaeda in Pakistan to others.
The biggest change to the 2001 campaign that would have the biggest long term effect is not a bomb getting lucky and killing Bin Laden. It was keeping the majority of the jihadi movement that was for the most part held up in Afghanistan at the time from escaping and wiping out the Taliban leadership as well so we are talking about Bin Laden and his commanders, Mullah Omar and his commanders and Zarqawi and his commanders getting wiped out.
That could have happened, but we did Afghanistan after 911 too quickly and with too poor planning. It would be one thing in politics forced the WH's hand, but the public support was there for a lot more they just didn't know it yet and also they left the war in the hands of some very poor military planners.
