they don't need to fight a war of attrition.that's not how israelis conduct warfare. they go for the jugular and waste no time. they'll do whatever it takes regardless of rules. they've already obtained a carthaginian peace. it's over. hamas is mostly gone. hezbollah was shown to be a paper tiger and routed in a matter of days. iran shows that it's afraid of a fight and abandoned assad and its foothold in syria, which was its staging area to support proxy attacks on israel. it's not about numbers. they have the technology and equipment thanks to yours truly, and the trademark jewish cunning that's honor-based arab cultures are ill-prepared for. plus, they have the morale. you're in denial if you can't see it.
