An awful lot. In just about 130 years they've built the only functioning democracy in the Middle-East.
An excerpt from an answer that I gave to a related question: For 2014 Israel is on-track to have a GDP of $306-billion; per capita $38K (and this with no oil-wealth). The average per capita gross domestic product (GDP) of the fifty-seven countries that comprise the Organization of the Islamic Conference (OIC) is $5,746.00.
An excerpt from What Went Wrong? by Dr. Farrukh Saleem: “Over the past 105 years, 1.4 billion Muslims have produced eight Nobel Laureates while a mere 14 million Jews have produced 167. Muslims constitute 22 percent of the world population, but have only a 1 percent share of Nobel Prizes, whereas Jews constitute less than one quarter of one percent of world population with a 22 percent share of Nobel Prizes.”
Clearly the Israelis are doing something right – and they've accomplished what they have in about 130 years and with their neighbors trying to annihilate them.
