Presidential debate: top 10 quotes Mr Obama lampooned Mr Romney's promise to increase defence spending by two trillion dollars and build up the US Navy - a move which Mr Obama claimed failed to take into account the needs of modern warfare. Mr Obama said: "You mention that we have fewer ships than we had in 1916. Well, governor we also have fewer horses and bayonets, because that nature of our military has changed. On the issue of Afghanistan and al-Qaeda, Mr Obama and Mr Romney clashed repeatedly, with the president claiming Mr Romney's strategy was in a constant change of flux and in no way clear. Mr Obama said: "And you know, Governor Romney, I'm glad that you agree that we have been successful in going after al-Qaida, but I have to tell you that, you know, your strategy previously has been one that has been all over the map and is not designed to keep Americans safe or to build on the opportunities that exist in the Middle East." On Iraq, Mr Obama taunted Mr Romney again over his lack of experience at the helm. Mr Obama said: "I know you haven't been in a position to actually execute foreign policy -- but every time you've offered an opinion, you've been wrong. You said we should have gone into Iraq, despite that fact that there were no weapons of mass destruction. Referring to a comment made by Mr Romney, Mr Obama again sought to mock his opponent's political aptitude. Mr Obama said: "Governor Romney, I'm glad that you recognize that al-Qaida is a threat, because a few months ago when you were asked what's the biggest geopolitical threat facing America, you said Russia, not al-Qaida; you said Russia, in the 1980s, they're now calling to ask for their foreign policy back because, you know, the Cold War's been over for 20 years." In seemingly attempting to sum up his competitor, Mr Obama remarked: "Both at home and abroad, he (Mr Romney) has proposed...reckless policies. He's praised George Bush as a good economic steward and Dick Cheney as somebody who's -- who shows great wisdom and judgment. And taking us back to those kinds of strategies that got us into this mess are not the way that we are going to maintain leadership in the 21st century. Governor Mitt Romney: On the subject of Afghanistan Mr Romney laid out his strategy, saying: "Well, my strategy is pretty straightforward, which is to go after the bad guys, to make sure we do our very best to interrupt them, to -- to kill them, to take them out of the picture." On his methods for dealing with Russia, Mr Romney claimed: "I'm not going to wear rose-coloured glasses when it comes to Russia, or Mr. Putin. And I'm certainly not going to say to him, I'll give you more flexibility after the election. After the election, he'll get more backbone. On America's standing in the world, Mr Romeny said: "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. On the the use of military drones, Mr Romney said: "Well I believe we should use any and all means necessary to take out people who pose a threat to us and our friends around the world. And it's widely reported that drones are being used in drone strikes, and I support that and entirely, and feel the president was right to up the usage of that technology. On the issue of Iran, Mr Romney argued that the country was "four years closer to a nuclear weapon" and that Mr. Obama has "wasted" the last four years because "they continue to be able to spin these centrifuges and get that much closer."
