Despite providing the UN (and the public) with aerial photos of Hezbollah rockets in southern Lebanon, the UN peacekeeping force insists that they have seen no such weapons. But the UN also says that it is not its mission to search for Hezbollah weapons. That's the job of the Lebanese army, but the Lebanese avoid it. The army has caught a few trucks (apparently by accident) bringing in rockets, but generally looks the other way. Hezbollah has told the Lebanese government that there would be another civil war if the government interfered with the Hezbollah buildup in the south.
