FYI, Israel has extradited quite a few people, mostly related to fraud and drug dealing, e.g. http://www.jpost.com/National-News/Court-upholds-US-extradit... and http://www.haaretz.com/news/ze-ev-rosenstein-to-be-extradite...

A sad (or amusing, depending on your point of view) thing, actually - Israeli police has started begging the FBI a few years ago to ask Israel for extradition of Israeli drug dealers who had anything, even remotely, to do with the US - because the burden of evidence in a criminal case in Israel is so much heavier than in the US.

This is their plan B: Israeli police have been unable to get the conviction they wanted in cases which would have been cut-and-dry in the US. Israeli courts don't just trust blindly trust a cop's "I saw / I heard" evidence, and apply custody of evidence rules very strictly, which makes some (arguably just) convictions nearly impossible. (On the other hand, wrong convictions, though definitely exist, are probably much less frequent as a result)
