Isreal has been a major manufacturer of weapons for yonks. Israel’s industry is heavily dominated by high-technology, innovation, and advanced manufacturing, driven by a strong R&D sector and over 350 multinational centers (e.g., Intel, Apple, Google). Key sectors include electronics, cyber security, defense, pharmaceuticals, and chemical products. Despite limited natural resources, Israel has become a net exporter of natural gas. https://en.wikipedia.org/wiki/Economy_of_Israel
Also, like the Arab nations supplying petrol dollars to Arab militants, international Jewry, especially American Jewry, has been funding all sorts of things in Isreal.
