The area of climate change has a dramatic impact on national security.

My impression is that Putin feels that he can basically manipulate the West to do what he ultimately wants to achieve, and that he feels he's gotten away with it so far, and that all he has to do is basically play the same game.

I want to reassert again the position of the United States that with regards to Iran, we will not allow Iran to develop a nuclear weapon, period. We will not allow them to develop a nuclear weapon, and we will exert all options in the effort to ensure that that does not happen...The United States stands firmly with Israel, and we have a rock solid commitment to the security of Israel and to the security of its citizens.

I mean, the Taliban, my view is that they have been weakened.

China is a major power in the Pacific and I think we are dealing with some common threats in that region: the whole issue of Korea and the stability of Korea, the whole issue of nuclear proliferation, the whole issue of providing free access to our ships that are operating in that area.

Rather than undermining the Palestinian Authority, it is in Israel's interests to strengthen it by... continuing to transfer Palestinian tax revenues and pursuing other avenues of cooperation.
