“only the United States can do”
The Israels might utilize a large ship propeller shaft machined to a taper, a steel casing filled with explosive and a rocket acceleration system to make a bunker buster of their own to be dropped by an Israeli C-130.
Your makeshift bunker buster you want the Israelites to build needs 30,000 lbs of explosives. Do they have aircraft able to deliver two of them with stealth technology?
