We already know the results of the next Lebanon war and the excuses.

israel must have new and advanced weapons.
in particular, israel must have the capacity to blind
and silence the enemy while getting all the information she needs.
the enemy's ability to get any information regarding israel's
battle plans and all other war plans must be denied.
disinformation and spy craft need to be top level.
the psychological preparation of the soldiers need be enforced.
secret weapons and their use by different units must remain secret.

new chief of staff and planners need to devise plan to immobilize enemy trap defenses of ieds, antitank weapons, planted explosives. soldiers should not rush headlong which is what the enemy wants. immobilizing artillery shells, other scatter special munitions , robotic tripwire and thousands of drone tripwires need to be considered.
kochavi may be the man to do it.

locals who hate the enemy can be utilized in some fashion.
