The Israelis’ anger was, in part, about U.S. hypocrisy: The American ban came after years of secretly testing NSO’s products at home and putting them in the hands of at least one country, Djibouti, with a record of human rights abuses. But Israel also had its own interests to protect. To an extent not previously understood, Israel, through its internal export-licensing process, has ultimate say over who NSO can sell its spyware to. This has allowed Israel to make NSO a central component of its national-security strategy for years, using it and similar firms to advance the country’s interests around the world.
