(Reuters) - With its nuclear program beset as never before by sanctions, sabotage and assassination, Iran must now make a new addition to its list of concerns: One of the biggest conventional bombs ever built.
Boeing's 30,000-pound Massive Ordnance Penetrator (MOP), an ultra-large bunker buster for use on underground targets, with Iran routinely mentioned as its most likely intended destination, is a key element in the implicit U.S. threat to use force as a last report against Iran's nuclear ambitions.

Would that weapon, delivered in a gouging combination with other precision-guided munitions, pulverize enough rock to reach down and destroy the uranium enrichment chamber sunk deep in a mountain at Fordow, Iran's best sheltered nuclear site? A "second best" result might be merely to block the plant's surface entrances, securing its temporary closure, some said.
