Today, one of the greatest security challenges our nation faces is in Afghanistan and Pakistan. Our mission is to defeat al Qaeda and eliminate it from the region, stem the tide of radicalism in Pakistan and secure that country’s nuclear arsenal from terrorists and rogue actors. We must also prevent al Qaeda and its Taliban allies from reclaiming the safe haven in Afghanistan it used to attack us on September 11, tragically taking thousands of innocent lives. I was in favor of our military action against the Taliban-led government of Afghanistan after al-Qaeda’s horrific attack on the World Trade Center and the Pentagon on September 11. The Taliban provided support and a safe-haven to al-Qaeda. Striking back at members of al-Qaeda, and the Taliban who sheltered them, was an appropriate response.
