Israel as a nation state has an ongoing national security issue involving Iran. For the last twenty years or so, Iran has been covertly developing nuclear weapons. Iran is a country with a very low opinion of Israel and is generally diplomatically opposed to its existence. Their supreme leader has a habit of saying things like "Israel is a cancerous tumor of a state" that should be "removed from the region". Because of these and other reasons, Israel has assessed, however accurately, that if Iran successfully develops nuclear weapons, it stands a not-insignificant chance of using them against Israel. Israel's response to this problem has been multi-pronged. Making defense systems that could potentially defeat Iranian nuclear weapons is an important component of their strategy. The country has developed a sophisticated array of missile interception systems like the Iron Dome. Some people even suggest that these systems would be effective against much of the incoming rain of hellfire from an Iranian nuclear state. But Israel's current evaluation of the "nuclear defense problem" is pretty pessimistic. Defense isn't all it has done. Given the size of Israel as a landmass, it would be safe to say that it's probably not the most important component of Israel's strategy. It has also tried to delay, or pressure Iran into delaying, its nuclear efforts through other means. For example, it gets its allies to sanction Iran, sabotages its facilities, and tries to convince its nuclear researchers to defect. In my model, an argument like "well, what's the point of all this effort, Iran is going to develop nuclear weapons eventually anyways" would not be very satisfying to Israeli military strategists. Firstly, that the Iranians will "eventually" get nuclear weapons is not guaranteed. Secondly, conditional on them doing it, it's not guaranteed it'll happen the expected lifetime of the people currently living in Israel, which is a personal win for the people in charge. Third
