Interception and destruction of Hizbollah 'drones' as far from heavily inhabited areas as possible should be considered a critical mission. Years ago (early 1980s) there was discussion within militant Shiite groups in Beruit of the use of drone aircraft to dispense biological agents in attempt to Terrorize Israelis citizens. I doubt the idea has entirely evaporated there. The methodology is a poor one, and very unlikely to yield substantial results. But it simply cannot be dismissed. Reasonable vigilance can remove this potential threat. Citizens shouldn't be worried, as the method is highly unlikely to prove effective. But failure to prevent such an attack, were it to become known such was attempted, would likely lead to a vast escalation in the level and scope of tensions, and could well lead to dramatic expansion of the scope of the conflict. This risk can be avoided by ensuring 'Hizbollah' drones wind up in the ocean or hills long before getting anywhere near cities.
