If we have learned nothing else from the 20th century, we should at least have grasped that the more perfect the answer, the more terrifying its consequences. Incremental improvements upon unsatisfactory circumstances are the best that we can hope for, and probably all we should seek.

American social arrangements, economic arrangements, the degree of inequality in American life, the relatively small role played by the government in American public life and so forth, compares to exactly the opposite conditions in most of the European societies.

Contrast 1968, when the CEO of General Motors took home, in pay and benefits, about sixty-six times the amount paid to a typical GM worker. Today the CEO of Wal-Mart earns nine hundred times the wages of his average employee. Indeed, the wealth of the Wal-Mart founder's family in 2005 was estimated at about the same ($90 billion) as that of the bottom 40% of the US population: 120 million people.

Although the United States lost a quarter of a million men and women, civilians and soldiers, in World War II, that's considerably less than the Russians lost in soldiers at the Battle of Stalingrad alone. It's important to convey to countries and to people and to generations who have no experience of the 20th century as it was lived in Europe just how catastrophic it was.

History can show you that it was one pile of bad stuff after another. It can also show you that there's been tremendous progress in knowledge, behaviour, laws, civilisation. It cannot show you that there was a meaning behind it.

I was born accidentally. I lived accidentally in London. We nearly migrated to New Zealand. So much of my life has been a product of chance, I can't see a meaning in it at all.

The American financial and military commitment really only kicks in with Korea. Not that Korea was the real game for the Americans; their real fear was that this was just the prelude to a second Korea in Germany. We now know from the Soviet archives that the last thing Stalin was going to do was start a war in Central Europe. The Americans didn't know that, and it was the fear that he might which transformed NATO from a sort of shell game into a real military alliance. That total commitment basically transformed the Marshal Plan into military aid.
