Hezbollah’s deadly attack against an army base deep inside Israeli territory presents a major headache for Israel as it continues to struggle to defuse the threat posed by the group.

In addition to Iron Dome, systems such as Adam’s Sling, Arrow 2 and Arrow 3 are designed to destroy ballistic missiles. And they will soon be bolstered by the arrival of a Terminal High Altitude Area Defence (Thaad) battery from the United States which will be operated by nearly 100 US military personnel.

The drone attack was one of the deadliest attacks by the Iran-backed militant group since Israel launched its ground invasion of Lebanon nearly two weeks ago.
