Read the following context and choose the best option to answer the question.
Context: I am glad that Democrats like Barack Obama think that it is important to win our fight against the Taliban in Afghanistan , but I am bothered by the fact that virtually all Democrats pretend that al Qaeda is resurgent there ( and has found safe haven there ) because we " took our eye off the ball " when we invaded al - Qaeda - free Iraq in 2003 .
