In the words of President Obama, "" If the Taliban take over again, they will invite back Al-Qaeda, who will try to kill as many of our people as they possibly can. "" 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.
