at crime library the following quote had me thinking (which is not always good this late)

"When the Trafficantes of Tampa tried to go in big on their own in Cuba, Lansky used his Batista connection to squash the move. Then he gave them a slice, smaller than what many other mafiosi got."(copyrighted to CrimeLibrary.com)

i was wondering how Lansky's Batista connection squashed the move and how big and what was the slice he gave them.
