"I wonder how many Iranian ships are getting through" - Yonatan Too many. This whole problem reminds me of a program an old friend was once involved in called Igloo White. They were using sophisticated sensors planted along the various Ho Chi Minh trails in Laos and monitoring them from EC-121R aircraft. The USAF was claiming huge bags of trucks, most of which were in fact not harmed. The horrible thing was that it only took a few trucks a day getting through to supply the minimum needs of the Viet Cong. The best we could hope to achieve was to make it costly and slow buildups for offensive operations. That is all that may be done to stop resupply of Hizbollah. The goal for decades has been to keep the Lebanese Army weak, and the Lebanese government is barely functional. Smuggling from Syria is very difficult to control. Smuggling from Iran to Syria is a bit easier to deal with as we have seen. Too many ships are getting through. Hizbollah is Iran's cheap deterrent.
