The Tel Aviv cluster: Israel's greatest strength -- and weakness

As Dan Senor and Saul Singer write in “Start-Up Nation: The Story of Israel’s Economic Miracle,” Israel now has a classic innovation cluster, a place where tech obsessives work in close proximity and feed off each other’s ideas.

Because of the strength of the economy, Israel has weathered the global recession reasonably well. The government did not have to bail out its banks or set off an explosion in short-term spending. Instead, it used the crisis to solidify the economy’s long-term future by investing in research and development and infrastructure, raising some consumption taxes, promising to cut other taxes in the medium to long term. Analysts at Barclays write that Israel is “the strongest recovery story” in Europe, the Middle East and Africa…

The tech boom also creates a new vulnerability. As Jeffrey Goldberg of The Atlantic has argued, these innovators are the most mobile people on earth. To destroy Israel’s economy, Iran doesn’t actually have to lob a nuclear weapon into the country. It just has to foment enough instability so the entrepreneurs decide they had better move to Palo Alto, where many of them already have contacts and homes. American Jews used to keep a foothold in Israel in case things got bad here. Now Israelis keep a foothold in the U.S.
