One Option to Oil.
In this article there is an important lesson.
Israel is not a major oil producer. Many of its enemies are. These enemies are not democratic so they can spend lots of money on scud missiles, training terrorists etc., because they are not accountable to their people and economies for taxes. Sure, Israel is economically developed and has a high-tech military that has been supported by the US but their enemies have their sponsors too.
But it's interesting how a good education system and a commitment to science and technology research can be used to turn a disadvantage into an advantage.
I had heard about this technology being developed but I had not realized that Israel had brought it so far and answered so many of the practical questions.
