REPORTER: On Iraq, can the American people expect that by the end of your first term you will have affected a regime change in Iraq, one way or another? And by the same token --
DUBYA: That's hypothetical.
REPORTER: But can the American people expect that? Should they expect that?
DUBYA: That's a hypothetical question. They can expect me not to answer hypothetical questions.
REPORTER:On Osama bin Laden does your promise still --
DUBYA: On sensitive subjects.
REPORTER: Sir, on Osama bin Laden, does your promise still hold that he will be caught, dead or alive, at some point?
DUBYA: What? Say that again?
REPORTER: Does your promise on -- or your goal of catching Osama bin Laden dead or alive, does that still stand?
DUBYA: I don't know if he is dead or alive, for starters -- so I'm going to answer your question with a hypothetical. Osama bin Laden, he may be alive. If he is, we'll get him. If he's not alive, we got him.
