Giananca's high profile lifestyle and the loss of some of his loyal backers, put him at risk. His exile was self-imposed, but certainly Ricca and probably Accardo warned him of the dangers of remaining in Chicago at this time.

Giancana was tough and had a difficult time adjusting to change (IMO). He wanted to conduct business the old-fashioned way: corruption, extortion or murder. Times were changing in Chicago and it was necessary for The Outfit to adjust and modify their ways to allow for these changes. I believe Giancana had a very difficult time adjusting. Plus, he was very stubborn; it was his way, the highway or the grave. A real gangster for sure.
