To explain the unknown by the known is a logical procedure; to explain the known by the unknown is a form of theological lunacy.

Donald Trump is sitting on the control deck of the starship Enterprise, and he can push a lot of pretty buttons, but those buttons aren't connected to anything. And so nothing is happening.

I think the Barack Obama position and the majority position of American Jews and a lot of Americans is a two-state solution between Israel and Palestine. Settlements get in the way of that. If they're not stopped soon, there is no prospect for that type of solution.

The public is not only shifting from left to right. Every single idea associated with the educated class has grown more unpopular over the past year. . . . A year ago, the Obama supporters were the passionate ones. Now the tea party brigades have all the intensity.

I expect [Donald] Trump to do what he's done very successfully, which is, whether you like him or not, he will be the dominant player .

The things that make them similar - their machismo, their expansionary braggadocio - is going to turn them I think into bitter and dangerous enemies. We will look back on this moment where we thought Vladimir Putin and Donald Trump were sort of close as a moment of bitter irony, when they get into a schoolyard display against each other, amping up each other's worst tendencies and putting the two countries in some sort of scary position.

Putin is someone who has been undermining the norms of what we consider the world order since he got into power and in increasing success.
