hezbollah was created to protect lebanese from israel. all of their strengths are tunnels, rockets and guerilla warfare. and invasion from them makes no sense at all and plays to the idf/iaf strengths. now why didn't hezbollah actually use any of their higher end missiles and attack a desalination or power plant in israel (there are only 5 plants they get an entire country's clean water from) would be a fair question. hez and iran have capabilities to do real serious damage to israelis and they choose not to. is that cowardice or risk aversion or escalation management? idk
