If Hezbollah joins they know Israel will destroy Lebanon, don't forget Israel has also nuclear weapons, but it has not acknowledged its nuclear forces.
The Mossad is also very capable to assassinate enemies around the world even deep inside Iran.
israel will never use nuclear weapon. china and russia will use it the next second too and we have ww3
but if hezbollah will attack then yes lebanon will be in a huge problem. but if iran will attack then israel will be in a huge problem...
