"We have got to make sure that these weapons of mass destruction, that nuclear weapons are not given to those hands of [Iranian President Mahmoud] Ahmadinejad, not that he would use them, but that he would allow terrorists to be able to use them," she said.
Though seemingly flummoxed by the term, Palin agreed in principle to the "Bush doctrine," or the idea that the United States has the right to preemptively strike another country before first being attacked.
"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.
When asked whether the United States should be able to invade Pakistan in pursuit of terrorists along the Afghanistan border, Palin demurred.
"Is that a yes?" asked Gibson. "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 responded, saying: "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."
Palin defended a previous statement in which she reportedly characterized the war in Iraq as a "task from God."
Gibson quoted her as saying: "Our national leaders are sending U.S. soldiers on a task that is from God."
But Palin said she was referencing a famous quote by Abraham Lincoln.
"I would never presume to know God's will or to speak God's words. But what Abraham Lincoln had said, and that's a repeat in my comments, was let us not pray that God is on our side in a war or any other time, but let us pray that we are on God's side."
When asked if she believed she was "sending [her] son on a task that is from God," Palin said: "I don't know if the task is from God, Charlie. What I know is that my son has made a decision. I am so proud of his independent and strong decision he has made, what he decided to do and serving for the right reasons and serving something greater than himself and not choosing a real easy path where he could be more comfortable and certainly safer."
