March 1965 Vietnam. American fighter jets are taking off to bomb munitions depot in the North. A few days later, American ground troops arrive in the jungle. They would stay there for almost a decade, dropping more bombs on Vietnam than in all theatres of World War Two. How did this happen?

The answer lies with someone who has evaded the glare of the spotlight. A liberal development theorist called Walt Rostow. A man who started off by advocating to help developing nations become capitalist and who ended up helping to unleash hell on an unsuspecting civilian population of a country on the other side of the world.

This is a story of how idealism can lead to disaster. Of how America went from defender of freedom to bearer of destruction.

David Dimbleby tells the story of how, in the middle of the 20th century, one country - America - became a superpower and shaped the world around it.

It began with a vision. A vision born out of the ashes of World War Two. A vision of a world shaped not by war but by peace. This vision of America at the head of the free world came to be the defining idea at the center of the past 80 years of world politics. And yet now it is under threat.

So how did we get here? How did America become the leader of the free world and why did it go wrong? It’s a story shaped by people. People you have probably never heard of.

In the 20th Century, these ‘invisible hands’ wrote the story America came to believe about itself. A story of moral leadership leading to prosperity and peace. But is it a story that has run out of steam?
