The story that we're told is that there was a "light footprint" initially -- in other words, that we ended up in a situation where we didn't have enough troops, we didn't have enough resources, that Afghans were frustrated -- they felt there wasn't enough progress and economic development and security, and therefore the Taliban came back -- that we responded in 2005 and 2006 with troop deployments, but we still didn't put enough troops on the ground.
