Thanks a lot.

And we'll see how it all unfolds.

This is by far the biggest disruption of world oil that's ever occurred.

It's really hit Asia because essentially, from an economic terms, the Strait of Hormuz points east.

80% of the oil goes to Asia, 90% of the natural gas.

And for countries like Japan and South Korea and even China, as well as India, this is a very big slam to their economies.

I think you begin by not realizing what you're doing.

I mean, I agreed to do that book.

I said I'd do it in two years.

It took me seven years.

And the stories just became so compelling and it became woven in with the history of the 20th century.

And the funny thing was that some years before that, a publisher had flown up from New York to see me when I was teaching at Harvard and said she had a very interesting idea for a book.

And I said, what?

And she said, a history of the 20th century.

I said, that's an interesting idea.

And I thought to myself, it's...

rather broad and actually the century wasn't over yet at that point.

But I think somehow I think that was kind of in the DNA of the book.

And so as I told the story, it really was looking, it was not the history of the 20th century, but a history of the 20th century.

I think it's also, I mean, because I think geopolitics narrative.
