Iran provides the majority of Hezbollah's funding and weapons, flying them through Iraqi airspace to Syria. Syria supplies some advanced weaponry and permits Iran to use Damascus as a waypoint to supply the group. Iran flies most materiel into Damascus area airports and has it trucked overland to Hezbollah, with some material flown directly to Lebanese airports. Both Iran and Syria's support increased after the 2006 Lebanon War, with Iran's support increasing more. Hezbollah owes its unique military power to the logistical support of Iran. Hezbollah's purpose, in Iran's view, is to deter American or Israeli attacks on Iran's nuclear facilities.
