Also, any OC group will do business with any other group that can make them money, that has been proven time and time again. If a cartel or OMG or Italian mafia family can make money with the Gambinos they will do business with them, regardless of whether Cali is avenged or not. Again, this isn't a movie, money makes the world go round.
OC have done business with terrorists at home and in Italy. They have no standards about who they do business with.
Immediately after 9/11 they were thinking of ways to make money off that terrorist attack.
