The Hanover Institute for Public Policy is a website presenting itself as a think tank on Israel and Palestine, but its disclaimer says it was created for the Israeli Government Advertising Agency by Piro, Inc. The site has published more than 100 undated, unattributed reports since August 6, framing Israel-Gaza questions in a research-style format with footnotes, tables of contents, statistics, and citations. Piro describes a service called “AI Story Optimization” as authoring content engineered for how large language models assess credibility. NewsGuard analyst Alice Lee said the site appears designed to reach U.S. users through search engines and AI chatbots, which tend to favor concrete data and citations. Hanover reports challenge some claims critical of Israel, including UNICEF’s assessment of damage to Gaza’s water and institutional infrastructure, and often connect their subjects to antisemitism. The institute says its cited research is peer-reviewed and academic, while frequently citing Israeli government sources including the Israel Defense Forces and Ministry of Foreign Affairs. Piro has received $900,000 from the Israeli government through Havas Media, according to the reported filings. GPTZero classified 11 of 12 randomly selected Hanover reports as likely AI-written with high confidence and one with moderate confidence. Separately, Israel contracted former Trump campaign manager Brad Parscale under a $46.5 million deal to create pro-Israel websites intended to influence chatbot outputs; Drop Site reported that Copilot and Gemini had incorporated information from those sites.
