I find it moderately amusing that so many who haven't a clue as to the topography of the Tora Bora area, think it was so easy to just move in a few thousand troops and cut off any chance of a dozen guys on foot or horse back who knew ever little rock and shrub in the area, from sneaking out of that area. Hell they could have moved one mile to a different cave and we never would have found them.
We are talking about some of the most treacherous terrain in the entire world. Just try even using Google Earth and really look at the area.
You should see Gomel, Afghanistan. Not even the Taliban will go there.
It looks like the moon.
