ON U.S. POLICY IN THE MIDDLE EAST

Republican Mitt Romney: "I congratulate him on -- on taking out Osama bin Laden and going after the leadership in Al-Qaida. But we can't kill our way out of this mess."

President Obama: "We ended the war in Iraq, refocused our attention on those who actually killed us on 9/11. And as a consequence, Al Qaeda's core leadership has been decimated. In addition, we're now able to transition out of Afghanistan in a responsible way, making sure that Afghans take responsibility for their own security. And that allows us also to rebuild alliances and make friends around the world to combat future threats."

ON AMERICA'S ROLE IN THE WORLD

Romney: "Well, I -- I absolutely believe that America has a -- a responsibility and the privilege of helping defend freedom and promote the principles that -- that make the world more peaceful. And those principles include human rights, human dignity, free enterprise, freedom of expression, elections, because when there are elections, people tend to vote for peace."

Obama: "America remains the one indispensable nation. And the world needs a strong America. And it is stronger now then when I came into office. Because we ended the war in Iraq, we were able to refocus our attention on not only the terrorist threat but also beginning a transition process in Afghanistan. It also allowed us to refocus on alliances and relationships that had been neglected for a decade."

ON SYRIA

Romney: "Seeing Syria remove [President Bashar] Assad is a very high priority for us. Number two, seeing a -- a replacement government being responsible people is critical for us. And finally, we don't want to have military involvement there. We don't want to get drawn into a military conflict. And so the right course for us is working through our partners and with our own resources to identify responsible parties within Syria, organize them, bring them together in a ... if not government, a form of council that can take the lead in Syria, and then make sure they have the arms necessary to defend themselves."

Obama: "What we've done is organize the international community, saying Assad has to go. We've mobilized sanctions against that government. We have made sure that they are isolated. We have provided humanitarian assistance, and we are helping the opposition organize."

ON DEFENSE SPENDING

Romney: "Our Navy is smaller now than at any time since 1917. The Navy said they needed 313 ships to carry out their mission. We're now at under 285. We're headed down to the low 200s if we go through a sequestration. That's unacceptable to me."

Obama: "Governor, we also have fewer horses and bayonets because the nature of our military's changed. We have these things called aircraft carriers where planes land on them. We have these ships that go underwater, nuclear submarines. And so the question is not a game of Battleship where we're counting ships."
