Trump considers using ‘mother of all bombs’ against Iran as president faces pressure to end the war | 15 Oct 2026 | President Donald Trump is considering unleashing America’s most powerful non-nuclear bomb against Iran in a devastating new assault as pressure mounts to end the deeply unpopular war. The Pentagon has developed plans to deploy the 21,600-pound “mother of all bombs” against Iranian nuclear facilities and energy infrastructure in what would represent a dramatic escalation of the six-month conflict. The enormous weapon, officially known as the GBU-43/B Massive Ordnance Air Blast bomb, or MOAB, is capable of devastating an area equivalent to nine city blocks. The president has publicly pledged not to launch fresh attacks before voters head to the polls, although some advisers privately question whether that promise will hold.
