According to a report from Axios, U.S. President Trump’s is said to have doubts about the whether the U.S. Air Force’s GBU-57A/B MOP (Massive Ordnance Penetrator) would actually be able to reach and destroy the Fordow Fuel Enrichment Plant (FFEP), Iran’s primary facility for enriching weapons-grade uranium, which is believed to be up to 90 meters deep inside a mountain near the city of Qom in Northern Iran. Trump is said to have specifically asked his military advisers over the last few days about whether the 30,000lb “bunker buster” would be capable of destroying the Fordow Nuclear Facility, with defense officials telling the President they are confident it would, though it’s not known if President Trump was convinced, “The bunker buster will work. It's not a capabilities issue. We have the capability. But there's an entire plan (for a possible attack). It's not just drop a bunker buster and declare victory,” a top U.S. official said.

Israeli officials believe that the United States will eventually join the war and assist with the destruction of the Fordow Facility, but contend they could cause significant damage to the underground complex even if forced to go it alone. One option could be a commando raid against the Fordow Nuclear Facility by Israeli special forces, similar to the operation seen last September where Israeli forces raided and destroyed an underground missile factory to the north of the Syrian capital of Damascus. A U.S. official said the Israelis told the Trump administration that while they may not be able to reach deep enough into the mountain with bombs, they may “do it with humans.”
