There seems to be a lot of evidence that Iran is supplying them with weapons.
Well, a dozen years ago there were attacks on israeli targets in Argentina, IIRC - and these were traced to Iran. Thus, the continuing existence of the iranian embassy in Beirut is an oversight, best to be corrected by daytime bombing, when the vermin are in.
Nice target list. Especially the Iranian embassy in Beirut.
