Location, location and how the West was won

From the BBC

"On his current visit to Beijing, UK Prime Minister David Cameron has said China will soon reclaim its position as the world's biggest economy - a role it has held for 18 of the past 20 centuries. But how did the US, Britain and the rest of Europe interrupt this reign of supremacy? It comes down to location.

Why does the West dominate the world?

Europeans have been asking this question since the 18th Century, and Africans and Asians since the 19th. But there is still not much agreement on the answers."
