Hezbollah is huge just like the the PLO and Hamas. It runs hospitals, schools, etc. It’s not just a terrorist group only. It is a quasi-state really. Not to mention the fact that some experts say Hezbollah gets anywhere from 60 to 200 million dollars a year from Iran. They most certainly would need a CFO.
I didn't know Iran has powers of arrest in Lebanon? That's a little extra territorial isn't it?
