The business lines of Hezbollah are mainly of criminal nature: trading drugs, weapons and handling stolen goods. Most terrifying is the trade of slaves and women, mostly in South America and Arab countries. Hezbollah is acting in the role previously held by Arab trade people.

PS: members of Hezbollah are NOT fighters. They are coward terrorists.

not even their criminal enterprises can save them.
