We have actually experienced in recent months a dramatic demonstration of an unprecedented intelligence failure, perhaps the most significant intelligence failure in the history of the United States.

The United States is prepared really to be engaged in the quest to get people in the world the dignities that they seek today, the social justice that they feel they're deprived of, and the common solution to global problems.

I think it is important to ask ourselves as citizens, not as Democrats attacking the administration, but as citizens, whether a world power can really provide global leadership on the basis of fear and anxiety?

Today, with America being a beleaguered global power, in part because of its own mistakes, it is absolutely essential that the American democracy refocuses its concerns towards global issues and does not approach its own specific problems on the basis of, to some extend, self-induced fear.

I think the US has the right to have its own national security policy. I think most Americans would agree with that. And therefore clarity on this issue is important and especially if we commit ourselves, explicitly and bindingly, to Israel's security.

Yes, ISIS is a threat. It's more than a nuisance. It's also in many respects criminal violence. But it isn't, in my view, a central strategic issue facing humanity.

One thing we know: Things will become even more destabilized if we don't step up Sino-U.S. cooperation. If you want to envisage a worst-case scenario, it is that Putin reveals step by step the inner weaknesses of the West, particularly in Europe, and the Chinese see in that an opportunity for emulation in the Far East, and then step by step through a gradual process we will be witnessing the emergence of Sino-Russian partnership in favor of a drastic change in the global balance of power.
