In a video released by Hezbollah, a large tunnel system is visible containing numerous missile launchers and military personnel. Trucks loaded with multiple missile launchers are also seen.
And a "very important detail": all of this was built in southern Lebanon, a region that has been under the responsibility of a UN peacekeeping mission for nearly 50 years. There are about 10,000 UN soldiers who, with an annual budget of half a billion dollars, are supposed to prevent terrorist groups from establishing themselves in southern Lebanon.
How the Lebanese terrorists of Hezbollah managed to build all this in an area supposedly guarded by 10,000 UN soldiers is a "mystery."
