 Iraq apparently believed it would rid itself of those Jews it regarded as the most troublesome, especially the Zionists, but retain the wealthy minority who played an important part in the Iraqi economy.Israel mounted an operation called "Ezra and Nehemiah" to bring as many of the Iraqi Jews as possible to Israel, and sent agents to Iraq to urge the Jews to register for immigration as soon as possible.The initial rate of registration accelerated after a bomb injured three Jews at a café.
