The Jewish exodus from Iraq was influenced by, and coincided with, a wave of bombings which took place between April 1950 and June 1951. These bombings damaged both Jewish and American targets, produced a number of serious injuries, and caused the deaths of six Iraqi Jews.
According to a number of anti-Zionist authors, the bombings were perpetrated by Zionist agents in order to cause fear amongst the Jews, and so promote their exodus to Israel (Black Panthers 1975:128-132; Hirst 1977:155-164; Eveland 1980:47-49; Wolfsohn 1980:186-201; Shapiro 1984:37-38; Avnery 1986:135-136; Shiblak 1986:119-127; Shohat 1988:12; Giladi 1993; Cohen 1998:111).
Some evidence for this argument is provided by the fact that the Iraqi authorities charged three members of the Zionist underground with perpetrating the explosions. Two Jews were subsequently found guilty and executed, whilst a third was sentenced to a lengthy jail term (Gat 1997:173-175).
The historian Moshe Gat argues convincingly (in my opinion) that there was little direct connection between the bombings and exodus. He demonstrates that the frantic and massive Jewish registration for denaturalization and departure was driven by knowledge that the denaturalization law was due to expire in March 1951.
He also notes the influence of further pressures including the property-freezing law, and continued anti-Jewish disturbances which raised the fear of large-scale pogroms. In addition, it is highly unlikely the Israelis would have taken such measures to accelerate the Jewish evacuation given that they were already struggling to cope with the existing level of Jewish immigration (Gat 1987:395; Gat 1997:182-187; also Meir-Galitzenstein 1988:235).
Gat also raises serious doubts about the guilt of the alleged Jewish bomb throwers. Firstly, a Christian officer in the Iraqi army known for his anti-Jewish views, was arrested, but apparently not charged, with the offences. A number of explosive devices similar to those used in the attack on the Jewish synagogue were found in his home. In addition, there was a long history of anti-Jewish bomb-throwing incidents in Iraq.
Secondly, the prosecution was not able to produce even one eyewitness who had seen the bombs thrown. Thirdly, the Jewish defendant Shalom Salah indicated in court that he had been severely tortured in order to procure a confession (Gat 1997:180-181 & 187-188; Gat 2000:11-13; also Hillel 1987:277-282; Meron 1995:51).
It therefore remains an open question as to who was responsible for the bombings, although Gat suggests that the most likely perpetrators were members of the anti-Jewish Istiqlal Party (Gat 1997:187; Gat 2000:20).
