Thats right and it is possible that during the 50s, 60s and probably 70s, Chicago was the leading family in the CIA and international ventures, followed by Trafficante/Tampa. Although we can also include the Genoveses and their previous OSS connections during the WWII. The alliance between the Genoveses and Chicago was simply incredible as a worldwide criminal force.
The CIA and French secret services set a good example working with underworld, now it's common practise among intelligence world wide.
