Hezbollah and Iran are the same thing.
Hezbollah is a Shia movement that is funded and trained by the Iranian Revolutionary Guard. Hezbollah's "spiritual leadership" are the Ayatollah's of Iran. Iranian sodiers often command units of Hezbollah fighters. Whether the Iranians did this themselves or chose not to get their hands dirty and had a Hezbollah operative do this is totally irrelevant.
Ohhh, now I see whether the "Iranians" did this themselves or chose not to get their hands dirty is irrelevant. Interesting!
