During the Republican candidates' debate on October 9, 2007, Chris Matthews asked Senator John McCain, "... Do you believe that Congress has to authorize a strategic attack, not an attack on-during hot pursuit, but a strategic attack on weaponry in Iran-do you need congressional approval as commander and chief?" Read McCain's response, then arrange its subarguments in standard form so as to reveal the structure of his argument. Then diagram the overall argument.
McCain: We're dealing, of course, with hypotheticals. If the situation is that it requires immediate action to ensure the security of the United States of America, that's what you take your oath to do, when you're inaugurated as president of the United States. If it's a long series of build-ups, where the threat becomes greater and greater, of course you want to go to Congress; of course you want to get approval, if this is an imminent threat to the security of the United States of America. So it obviously depends on the scenario. But I would, at minimum, consult with the leaders of Congress because there may come a time when you need the approval of Congress. And I believe that this is a possibility that is, maybe, closer to reality than we are discussing tonight. ${ }^4$
