Upon reflection, I did use the term "drawn down the forces" way too loosely and should've just said "let up the pressure" as I later did. Fair enough, and I'll take my chops on that. However, on the fact that Bush did prioritize Iraq and thus reduced the pressure (Thus giving the Taliban time to reform and become effective again), my link as well as yours does confirm that. He keep between 10 and roughly 25k troops in the operational zone, and the end result was severe overstretch and the crisis we saw starting around 2009 as the Taliban had years to rebuild.
The US forces in Afghanistan weren't overstretched since only the southern most provinces (still most populous in Afghanistan) were under the direct supervision of the United States while the rest was divided by ISAF.
