But as the arms-control scholar Thomas Schelling once noted, two things are very expensive in international life: promises when they succeed and threats when they fail.

Alaska itself is an unusual state.

America's growth historically has been fueled mostly by investment, education, productivity, innovation and immigration. The one thing that doesn't seem to have anything to do with America's growth rate is a brutal work schedule.

Americans have so far put up with inequality because they felt they could change their status. They didn't mind others being rich, as long as they had a path to move up as well. The American Dream is all about social mobility in a sense - the idea that anyone can make it.

Conservatives used to believe in confronting hard truths, not succumbing to comforting fairy tales. Some still do.

Culture follows power.

During the Cold War, we were interested because we were scared that Russia and the United States were going to go to war. We were scared that Russia was going to take over the world. Every country became a battleground.

I am an American, not by accident of birth but by choice. I voted with my feet and became an American because I love this country and think it is exceptional.

I don't want to paint a picture of total gloom and doom.

I grew up in Mumbai.

I grew up in this world where everything seemed possible.

I should not be judged by a standard that's not applied to everyone else.

I very much want to be in the business of creating content, of doing stories all over the world rather than figuring out what the business model is for 'Newsweek' on the iPad, although that's very important work as well.

I'd be kidding if I said that I predicted the financial collapse.

If a senator calls me up and asks me what should we do in Iraq, I'm happy to talk to him.

If there is one lesson for U.S. foreign policy from the past 10 years, it is surely that military intervention can seem simple but is in fact a complex affair with the potential for unintended consequences.

If we didn't have the rest of the world growing, the United States economy would be in much worse shape than it is today.

If you go to India the roads are being built almost entirely with private sector money and by the private sector. If you look at many, many countries in Europe that's how they're doing it.

In a very weak economy, when you say 'cut government spending,' what you mean is you're laying off school teachers and you're de-funding various programs that put money into the economy. This means you have more unemployed people that then draw unemployment benefits and don't pay taxes.

One of the great dilemmas for America will be that American companies will do very well while American workers might not.

One of the things that has been very difficult in Libya is the sense of uncertainty - the sense that they haven't actually finished the revolution, that there was still a great deal of uncertainty. That uncertainty has made Libya harder for business in terms of oil and other things as well.

The American consumer, even today, the weight of the American consumer in the global economy is China plus India doubled. So, it's tough to replace that.

The American dream seems to be thriving in Europe not at home.

The Chinese economy's still not that much of a consumer economy.

The United States is going to be a rich country, it is going to be prosperous, but it is not going to be able to take the lead in the next phase of global economic development.

The Web forces me to be disciplined and not to waste time - but before the Web was invented, there were plenty of opportunities to do that anyway.
