The introduction outlines the significance of the Dolphin submarine deal. Ranking among the world’s most advanced conventional submarines, the Dolphin-class submarines are Israel’s most expensive weapon system. They are manufactured in Germany. Just a few months after German reunification, which came with a heavy financial burden, the German government fully paid for two submarines for Israel. This was an extraordinary decision, especially given Germany’s delicate relations with Israel. Both countries share a special bond due to the Shoah. The book addresses two main questions: (1) How and why did Chancellor Kohl’s government reach the decision to approve an export permit for two submarines to Israel in 1989? (2) How and why did the government decide to pay for two submarines for Israel in 1991? Thus, the book focuses on the German decision-making process and the development of the Dolphin project from a German perspective. The introduction also includes a report on available sources and research, as well as a brief overview of the book.
