Bitzur was founded in the 1950s.
According to Ronen Bergman, Bitzur evacuated some 40,000 Jews from Iran in 1979-81.
According to Michael Ross, Bitzur was at one time, "headed by "Michel," a psychologist who had immigrated from France". This would have been in the latter part of Ross's career, which lasted from 1989 to 2001.
According to Yossi Melman and Dan Raviv, Bitzur became more active after 9/11 to respond to a wave of anti-semitic attacks around the world:
- Bitzur operatives were assigned to perform their traditional task of helping to organize self-defense for Jewish communities around the globe. This time, however, the task was almost always performed in conjunction with local police forces.
