ABC World News Tonight anchor Charles Gibson spoke to Republican vice presidential candidate Alaska Governor Sarah Palin in an exclusive multi-part interview that premiered on Thursday night.

The governor has sparked concerns that she does not know what the so-called Bush Doctrine is; the acceptance of preventive war; war waged not in response to evidence of an imminent attack; we have the right to attack a country that is not attacking us now but is likely to attack us at some point in the future.
