in terms of ground combat hezbollah and the iranians have the upper hand because tanks are not helping with all the anti tanks technology that they have so it's going to be hard to get in lebanon
and hezbollah soldiers have twice more experience after the syria war that they took part in.
they can get inside israel and make the 7/10 look like a walk in the park...

israel only advantage is their airforce which not help unless you destory anything there with no hesitation
because they hide underground.
thousands of israeli soldiers and citizens will die
tel aviv will be a graveyard
israel will have no choice but to strike hard and fast
