B2 bombers from Whiteman Air Force Base in Missouri carried out a strike Saturday night against Iran’s Fordow Nuclear Fuel Enrichment Plant, which was buried deep underground. This attack was the first time 30,000-pound Massive Ordnance Penetrators (MOPs), so-called “bunker busters,” have been used in combat.

The question is what comes next. Will Iran negotiate for peace and give up its ambition to develop a nuclear weapon?
