The Iranian Isfahan nuclear facility was not struck by bunker buster bombs; the reasons revealed by senior US military leaders.

Jin10 data, June 28 - According to CNN reports, informed sources said that General Dan Caine, Chairman of the Joint Chiefs of Staff of the United States, stated at a briefing last Thursday that the U.S. military did not use bunker busters on one of Iran's largest nuclear facilities last weekend because the site was too deep, and the bombs might not be effective. This statement was the first explanation for why the U.S. military did not use giant bunker busters on the Isfahan nuclear facility in central Iran. U.S. officials believe that the underground facilities in Isfahan hold nearly 60% of Iran's enriched uranium reserves, which Iran will need to produce nuclear weapons. The U.S. B2 bombers dropped dozens of bunker busters on Iran's Fordow and Natanz nuclear facilities. However, Isfahan was only hit by Tomahawk missiles launched from U.S. submarines.
