Hezbollah will likely respond severely but even with such responses. Israeli's will use incredibly high explosive bombs and drop them on civilians on purpose to kill up to a 1,000 civilians a day. Which can't be stopped unless someone else can kill up to 1,000 Israeli's a day, and keep it going. Or international sanctions are applied immediately. This kind of out control terrorist country is like Nazi Germany in WW2. In the beginning the scope of threat was underestimated. It can start a world war.
