Here's some of what aired on ABC's World News...
GIBSON: What insight into Russian actions, particularly in the last couple of weeks, does the proximity of the state give you?
PALIN: They're our next door neighbors and you can actually see Russia from land here in Alaska, from an island in Alaska.
GIBSON: Let me turn to Iran. Do you consider a nuclear Iran to be an existential threat to Israel?
PALIN: I believe that under the leadership of Ahmadinejad, nuclear weapons in the hands of his government are extremely dangerous to everyone on this globe, yes.
GIBSON: So what should we do about a nuclear Iran?
PALIN: We have got to make sure that these weapons of mass destruction, that nuclear weapons are not given to those hands of Ahmadinejad, not that he would use them, but that he would allow terrorists to be able to use them.So we have got to put the pressure on Iran.
GIBSON: What if Israel decided it felt threatened and needed to take out the Iranian nuclear facilities?
PALIN: Well, first, we are friends with Israel and I don't think that we should second guess the measures that Israel has to take to defend themselves and for their security.
GIBSON: So if we wouldn't second guess it and they decided they needed to do it because Iran was an existential threat, we would cooperative or agree with that.
PALIN: I don't think we can second guess what Israel has to do to secure its nation.
GIBSON: So if it felt necessary, if it felt the need to defend itself by taking out Iranian nuclear facilities, that would be all right.
PALIN: We cannot second guess the steps that Israel has to take to defend itself.
GIBSON: We talk on the anniversary of 9/11. Why do you think those hijackers attacked? Why did they want to hurt us?
PALIN: You know, there is a very small percentage of Islamic believers who are extreme and they are violent and they do not believe in American ideals, and they attacked us and now we are at a point here seven years later, on the anniversary, in this post-9/11 world, where we're able to commit to never again. They see that the only option for them is to become a suicide bomber, to get caught up in this evil, in this terror. They need to be provided the hope that all Americans have instilled in us, because we're a democratic, we are a free, and we are a free-thinking society.
GIBSON: Do you agree with the Bush doctrine? PALIN: In what respect, Charlie?
GIBSON: The Bush -- well, what do you -- what do you interpret it to be?
PALIN: His world view.
GIBSON: No, the Bush doctrine, enunciated September 2002, before the Iraq war.
PALIN: I believe that what President Bush has attempted to do is rid this world of Islamic extremism, terrorists who are hell bent on destroying our nation. There have been blunders along the way, though. There have been mistakes made. And with new leadership, and that's the beauty of American elections, of course, and democracy, is with new leadership comes opportunity to do things better.
GIBSON: The Bush doctrine, as I understand it, is that we have the right of anticipatory self-defense, that we have the right to a preemptive strike against any other country that we think is going to attack us. Do you agree with that?
PALIN: Charlie, if there is legitimate and enough intelligence that tells us that a strike is imminent against American people, we have every right to defend our country. In fact, the president has the obligation, the duty to defend.
GIBSON: Do we have the right to be making cross-border attacks into Pakistan from Afghanistan, with or without the approval of the Pakistani government?
PALIN: Now, as for our right to invade, we're going to work with these countries, building new relationships, working with existing allies, but forging new, also, in order to, Charlie, get to a point in this world where war is not going to be a first option. In fact, war has got to be, a military strike, a last option.
GIBSON: But, Governor, I'm asking you: We have the right, in your mind, to go across the border with or without the approval of the Pakistani government.
PALIN: In order to stop Islamic extremists, those terrorists who would seek to destroy America and our allies, we must do whatever it takes and we must not blink, Charlie, in making those tough decisions of where we go and even who we target.
GIBSON: And let me finish with this. I got lost in a blizzard of words there. Is that a yes? That you think we have the right to go across the border with or without the approval of the Pakistani government, to go after terrorists who are in the Waziristan area?
PALIN: I believe that America has to exercise all options in order to stop the terrorists who are hell bent on destroying America and our allies. We have got to have all options out there on the table.
