Just four years ago, the defense establishment decided to carry out a seemingly elementary task: establish a comprehensive database on the settlements. Brigadier General (res.) Baruch Spiegel, aide to then defense minister Shaul Mofaz, was put in charge of the project. For over two years, Spiegel and his staff, who all signed a special confidentiality agreement, went about systematically collecting data, primarily from the Civil Administration. One of the main reasons for this effort was the need to have credible and accessible information at the ready to contend with legal actions brought by Palestinian residents, human rights organizations and leftist movements challenging the legality of construction in the settlements and the use of private lands to establish or expand them. The painstakingly amassed data was labeled political dynamite.
