START-UP NATION addresses the trillion dollar question: How is it that Israel - a country of 7.1 million, only 60 years old, surrounded by enemies, in a constant state of war since its founding, with no natural resources— produces more start-up companies than large, peaceful and stable nations like Japan, China, India, Korea, Canada and the UK?

In a world where economies as diverse as Ireland, Singapore and Dubai have tried to re-create the "Israel effect", there are entrepreneurial lessons well worth noting. As America reboots its own economy and can-do spirit, there's never been a better time to look at this remarkable and resilient nation for some impressive, surprising clues.
